عَنْ أَبِي سَعِيدٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: " إِذَا رَأَيْتُمُ الرَّجُلَ يَتَعَاهَدُ الْمَسْجِد فَاشْهَدُوا لَهُ بِالْإِيمَان فَإِن الله تَعَالَى يَقُولُ (إِنَّمَا يَعْمُرُ مَسَاجِدَ اللَّهِ مَنْ آمَنَ بِاللَّه وَالْيَوْم الآخر وَأقَام الصَّلَاة وَآتى الزَّكَاة)
رَوَاهُ التِّرْمِذِيّ وَابْن مَاجَه والدارمي
Abud Darda' and Abu Dharr reported God’s Messenger as stating that God who is blessed and exalted said, “Son of Adam, if you perform four rak'as for me at the beginning of the day, I will supply what you need till the end of it.” Tirmidhi transmitted it, Abu Dawud and Darimi transmitted it from Nu'aim b. Hammar al-Ghatafani, and Ahmad from them all.
