On the authority of Abu Hurrairah (radiallaahu ‘anhu): The Prophet (salallaahu ‘alaihi wa sallam) said:
The one who looks after a widow or a poor person is like a Mujaahid (fighter) who fights for Allaah’s cause, or like him who performs prayers all the night and fasts all the day.
[Sahih Bukhaaree; The Book of Supporting the Family – Volume 7, Book 64, Number 265]
[Translator: M. Muhsin Khan]
Sahih Bukhari: Volume 2, Book 13, Number 33:
Narrated Salman Al-Farsi: Allah’s Apostle (sallallaahu alaihi wa sallam) said,
“Anyone who takes a bath on Friday and cleans himself as much as he can and puts oil (on his hair) or scents himself; and then proceeds for the prayer and does not force his way between two persons (assembled in the mosque for the Friday prayer), and prays as much as is written for him and remains quiet when the Imam delivers the Khutba, all his sins in between the present and the last Friday will be forgiven.”

Narrated ‘Ubada bin As-Samit: The Prophet -sallAllaahu alayhi wa sallam-said:
“Whoever gets up at night and says: —
لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَه،ُ لَهُ الْمُلْكُ وَلَهُ الْحَمْد،ُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ
سُبْحَانَ اللَّهِ ، وَالْحَمْدُ لِلَّهِ ، وَلَا إِلَهَ إِلَّا اللَّهُ ، وَاللَّهُ أَكْبَرُ ،وَ لَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللَّهِ
‘There is none worthy of worship in truth except Allaah Alone, He has no partners, He has the Dominion and for Him is all praise, and He is capable of all things, praise is for Him, and Far is Allaah from imperfection, and There is none worthy of worship in truth except Allaah, and Allaah is the Greatest, there is no capability nor is there any power except with Allaah.
La ilaha ‘illa Allaahu wahdahu la shareeka lahu, lahul mulku wa lahul hamdu wa huwa ala kulli shayin qadeer Subhana allaahi, wal hamdu lillaahi, wa la illaah ila Allaah, wa Allaahu akbar, La hawla wa la quwwata illa billaa
Then he says : اللهمَ اغْفِرْلي O Allaah forgive me (Allaahumma aghfirlee), or he supplicates and his supplication is answered, and if he makes Wudu and prays then his prayer is accepted.
