Mishkat al-Masabih #195

He also reported God’s messenger as saying, “ If anyone removes one of the anxieties of this world from a believer, God will remove one of the anxieties of the day of resurrection from him; if one smooths the way for one who is destitute, God will smooth the way for him in this world and the next; and if anyone conceals the faults of a Muslim, God will conceal his faults, in this world and the next. God helps a man as long as he helps his brother. If anyone pursues a path in search of knowledge, God will thereby make easy for him a path to paradise. No company will gather in a mosque to recite God’s Book and study it together without calmness descending on them, mercy covering them, the angels surrounding them, and God mentioning them among those who are with Him. But he who is made slow by his actions will not be speeded by his genealogy.” Muslim transmitted it.
