Is this narration sound?
المؤمن للمؤمن كالبنيان، يشد بعضه بعضا
‘The believers are like a building, they support and strengthen each other’
Imam Bukhari and Imam Muslim (rahimahumallah) have recorded this narration on the authority of Sayyiduna Abu Musa (radiyallahu ‘anhu). The narration is therefore authentic.
(Sahih Bukhari, Hadith: 481, 6026 and Sahih Muslim, Hadith: 2585)
This Hadith refers to assisting and supporting a Muslim with regards to his affairs of the Hereafter as well his permissible needs of this world. Something that it greatly needed in the world today.
(Refer: Fathul Bari, Hadith: 6026)
