The important time of Ramadan should not be wasted in unnecessary activities, but the time should be valued and utilized, especially the certain practices mentioned, should be tried to be careful.

1. Fasting: Ramadan fasting. Because Allah Ta'ala says about fasting, Fasting is for Me and I myself will replace it.

https://muslimbangla.com/hadith/1790

2. Tarawi prayer: Twenty rakat Tarawi prayer after Isha prayer. Since the era of Khulafay Rashedin, the practice of performing twenty rakats of Tarawi prayer has been going on and all the ummahs from the East have been practicing it for ages. In Haramain Sharif also the Amal is upheld on him. So we should also pray twenty rak'at tarabee prayers in this blessed month following the path followed by Sahaba Keram, Tabeen, Tabe-Tabeen, Aymaye Mujtahidin.

3. Performing Tahajjud Prayer: Naturally we all wake up to have Sehri on the last night. This is a very blessed time. So it is better to perform Tahajjud as many rakats as possible from four to twelve rakats. Tahajjud prayer became a habit of Rasulullah Sallallahu Alayhi Wasallam. Sahabah Keram also recited Tahajjud regularly.

Taraweeh and Tahajjud are not the same prayer

Many people try to prove Taraweeh by praying Tahajjud. But actually there is a substantial difference between the two prayers. Taraweeh and Tahajjud are not the same prayer.

4. Sitting in the mosque after Fajr till sunrise: The Messenger of Allah (peace and blessings of Allah be upon him) used to sit in the mosque after Fajr till sunrise (Muslim Sharif). Hazrat Anas (ra) said that the Messenger of Allah (peace and blessings of Allah be upon him) used to sit in the mosque after Fajr until sunrise (Muslim Sharif). Hazrat Anas (ra) said that the Messenger of Allah (peace and blessings of Allah be upon him) said, "This is about other months. In Ramadan, the reward will increase many times more. Recitation of Quran more: Recitation of Quran more in this month and concentration during recitation should be done. Hazrat Jibraeel (a.s.) used to recite the Qur'an with the Prophet (peace and blessings of Allah be upon him) during the month of Ramadan. If possible, read the translation of the Quran with the advice of a learned scholar.

5. Recitation of Quran more: Recitation of Quran more in this month and concentration during recitation should be done. Hazrat Gabriel (A.S.) used to recite the Qur'an with the Prophet (SAW) during the month of Ramadan. If possible, read the translation of the Qur'an with the advice of a learned scholar.

In the hadith:

وَعَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: الصِّيَامُ وَالْقُرْآنُ يَشْفَعَانِ لِلْعَبْدِ يَقُولُ الصِّيَامُ: أَيْ رَبِّ إِنِّي مَنَعْتُهُ الطَّعَامَ وَالشَّهَوَاتِ بِالنَّهَارِ فَشَفِّعْنِي فِيهِ وَيَيَقُولُ الْقُرْآنُ فَشَفِّعْنِي فِيهِ فيشفعان . رَوَاهُ الْبَيْهَقِيّ فِي شعب الْإِيمَان

1963 On the authority of Hazrat Abdullah Ibn Amr (RA), the Messenger of Allah (ﷺ) said: Fasting and the Qur'an will intercede with Allah for a servant (on the Day of Resurrection). Fasting will say, come to God! I have restrained him from his food and appetite during the day. So accept my intercession regarding him and the Qur'an will say, I prevented him from sleeping at night. So accept my recommendation regarding him. Therefore, both recommendations will be accepted. —Bayhaqi Shoabul Iman

6. Giving charity: Rasulullah Sallallahu Alayhi Wasallam was the most charitable. And in Ramadan, charity becomes more extensive. Hazrat Anas (ra) said, the Messenger of Allah (peace and blessings of Allah be upon him) said that giving charity in the month of Ramadan is the best charity.

So we should give more charity in this month. It can be in different ways - feeding the poor, fasting and iftar etc.

Hadith:

حَدَّثَنَا عَبْدَانُ, قَالَ أَخْبَرَنَا عَبْدُ اللَّهِ, قَالَ أَخْبَرَنَا يُونُسُ, عَنِ الزُّهْرِيِّ, ح وَحَدَّثَنَا بِشْرُ بْنُ مُحَمَّدٍ, قَالَ أَخْبَرَنَا عَبْدُ اللَّهِ, قَالَ أَخْبَرَنَا يُونُسُ, وَمَعْمَرٌ, عَنِ الزُّهْرِيِّ, نَحْوَهُ قَالَ أَخْبَرَنِي عُبَيْدُ اللَّهِ بْنُ عَبدِ اللَّهِ عَنِ ابْنِ عَبَّاسٍ, قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلمِ أَجْوَدَ النَّاسِ, وَكَانَ اَجْوَدُ مَا يَكُونُ فِي رَمَضَانَ حِينَ يَلْقَاهُ جِبْرِيلُ, وَكَانَ يَلْقَاهُ فِي كُلِّ لَيْلَةٍ مِنْ رَمَضَانَ فَيُدَارِسُهُ الْقُرْانَ, فَلَرَسُولُ اللَّهِ صلى الله عليه وسلم اَجوَدُ بِالْخَيْرِ مِنَ الرِّيحِ الْمُرسَلةِ.

5. Abdan (RA).... and Bishar Ibn Muhammad (RA) ... on the authority of Ibn Abbas (RA), he said, The Messenger of Allah (ﷺ) was the greatest giver. He used to be more charitable during Ramadan, when Jibraeel (peace be upon him) met him. And every night of Ramadan, Gabriel (Alaihis Salam) used to meet him and they would recite the Qur'an to each other. Surely the Messenger of Allah (ﷺ) was more generous than the wind of mercy.

Explanation of hadith:

The month of Ramadan is the month of charity: Charity is always the best deed, but its importance increases a lot in Ramadan. There is a Hadith Sharif - 'Rasulullah Sallallahu Alaihi Wasallam was more charitable than all the people of the world. In the month of Ramadan, his hand of charity was extended.' -Sahih Bukhari.

7. Performing I'tikaf in the Last Decade: Men will perform I'tikaf in mosques and women in their home prayer places. The Messenger of Allah (peace and blessings of Allah be upon him) used to perform I'tikaf in the last ten days of every Ramadan. There is more discussion about Itikaaf ahead.

8. Shabqadar: There is a night in the month of Ramadan called Shabaqadar. That night's worship is better than a thousand years. And that night should be sought in the odd nights of the last decade of Ramadan.

9. Making Dua'r Ihtemam: Dua is a high level of worship. The Prophet (peace be upon him) said, Dua is the brain of all worship. The main thing is to do more Ihtimam in the month of Ramadan.

On the authority of Hazrat Abu Saeed Khudri, the Messenger of Allah, may God bless him and grant him peace, said that every night and day of the month of Ramadan, Allah releases the prisoners of Hell and accepts at least one dua of every Muslim. Therefore, day and night whenever possible, especially on the last night during Iftar, one should pray for the welfare of one's world and the hereafter, seek forgiveness for the souls of the dead, seek the welfare of all Muslim men and women, and pray for the guidance of the infidels.

10. Do more of the four things.

1. Read more Kalima.

2. Reciting Estegfa more and more.

3. Liberation from hell

4. Make more dua to enter Jannah.
