Sunnahs to Follow in Ramadan
1. Waking up to have suhûr, even if it is something little. The Messenger of Allah, peace be upon him, said: "Eat suhûr for in suhûr there is blessing." [Narrated by al-Bukhârî and by Muslim]
2. Not delaying the iftâr. The Messenger of Allah, upon whom be peace, said: "The people will remain upon goodness as long as they hasten in breaking their fasts" [Narrated by al-Bukhârî and by Muslim]
3. Supplicating throughout the day and night, especially during iftâr time. The Messenger of Allah, peace be upon him, said: "Three prayers are not rejected: the prayer of a father, the prayer of a fasting person, and the prayer of a traveller." [Narrated by al-Bayhaqi 3/345]
4. Spending the nights in prayer, as well as encouraging the family to do so. The Messenger of Allah, peace be upon him, said: "Whoever establishes prayers during the nights of Ramadhân out of sincere faith and hoping to attain Allah's rewards, all his past sins will be forgiven." [Narrated by al-Bukhârî]
5. Being generous and feeding the people iftâr. The Messenger of Allah said: "Whoever gives iftâr to one who is fasting will have a reward like his, without detracting from the reward of the person fasting." [Narrated by al-Bukhârî and by Muslim]
6. Staying away from all immoral acts, especially those of the tongue. The Messenger of Allah, peace be upon him, said: "Fasting is not abstaining from eating and drinking alone, but it is also abstaining from vain speech and foul language. If one of you is being cursed or annoyed, he should say: I am fasting, I am fasting." [Narrated by al-Bukhârî and by Muslim]
7. Performing 'umrah. The Messenger of Allah, upon whom be peace, said: "Perform 'umrah when Ramadhân comes, for 'umrah in Ramadhân is equal to hajj (in reward)." [Narrated by al-Bukhârî]
