Volume 3, Number 622:
Narrated 'Abdullah bin Umar:
Allah’s Apostle (salla llahu alayhi wa sallam) said,
"A Muslim is a brother of another Muslim, so he should not oppress
him, nor should he hand him over to an oppressor. Whoever fulfilled
the needs of his brother, Allah will fulfill his needs; whoever
brought his (Muslim) brother out of a discomfort, Allah will bring
him out of the discomforts of the Day of Resurrection, and whoever
screened a Muslim, Allah will screen him on the Day of
Resurrection . " (Sahih Bukhari)
Volume 3, Number 626:
Narrated Abu Musa:
The Prophet (salla llahu alayhi wa sallam said,
“A believer to another believer is like a building whose different
parts enforce each other.”
The Prophet (salla llahu alayhi wa sallam)then clasped his hands with
the fingers interlaced (while saying that). (Sahih Bukhari)
“I put my trust in Allah, my Lord and your Lord! There is not a moving creature, but He has a grasp of its forelock. Verily, my Lord is on the straight path. (The truth)”
