[14].Surah Ibrahim {A.S} [Abraham (PBUH)]: Ayat 40-41

Ayat 40. "O my Lord! Make me one who performs As-Salat (Iqamat-as-Salat), and (also) from my offspring, our Lord! And accept my invocation.

Ayat 41. "Our Lord! Forgive me and my parents, and (all) the believers on the Day when the reckoning will be established."

 

Hazrat `Uthman bin `Affan (May Allah be pleased with him) reported: I heard the Messenger of Allah  [SAWW](PBUH) saying: "One who performs `Isha' prayer in congregation, is as if he has performed Salat for half of the night. And one who performs the Fajr prayer in congregation, is as if he has performed Salat the whole night.'' [Muslim]

The narration of At-Tirmidhi says: `Uthman bin Affan (May Allah be pleased with him) narrated that he had heard the Messenger of Allah  [SAWW](PBUH) saying: "He who attends `Isha' in congregation, is as if he has performed Salat for half of the night; and he who attends `Isha' and Fajr prayers in congregation, is as if he has performed Salat for the whole night.'' At-Tirmidhi Hadith # 221]. 

Lesson : as mentioned above in Surah Ibrahim {A.S} Ayat 40. ""O my Lord! Make me one who performs As-Salat" This Hadith tells us that the reward of performing `Isha' and Fajr prayers in congregation is so great that it equals the worship of the whole night.
