It was narrated that Abu Hurairah said:
"The Messenger of Allah said: 'Whoever relieves a Muslim of some worldly distress, Allah will relieve him of some of the distress of the Day of Resurrection, and whoever conceals (the faults of) a Muslim, Allah will conceal him (his faults) in this world and the Day of Resurrection. And whoever relives the burden from a destitute person, Allah will relieve him in this world and the next. Allah will help His slave so long as His slave helps his brother. Whoever follows a path in pursuit of knowledge, Allah will make easy fro him a path to paradise. No people gather in one of the houses of Allah, reciting the Book of Allah and teaching it to one another, but the angels will surround them, tranquility will descend upon them, mercy will envelop them and Allah will mention them to those who are with Him. And whoever is hindered because of his bad deeds, his lineage will be of no avail to him.'"
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَلِيُّ بْنُ مُحَمَّدٍ، قَالاَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏ "‏ مَنْ نَفَّسَ عَنْ مُؤْمِنٍ كُرْبَةً مِنْ كُرَبِ الدُّنْيَا نَفَّسَ اللَّهُ عَنْهُ كُرْبَةً مِنْ كُرَبِ يَوْمِ الْقِيَامَةِ وَمَنْ سَتَرَ مُسْلِمًا سَتَرَهُ اللَّهُ فِي الدُّنْيَا وَالآخِرَةِ وَمَنْ يَسَّرَ عَلَى مُعْسِرٍ يَسَّرَ اللَّهُ عَلَيْهِ فِي الدُّنْيَا وَالآخِرَةِ وَاللَّهُ فِي عَوْنِ الْعَبْدِ مَا كَانَ الْعَبْدُ فِي عَوْنِ أَخِيهِ وَمَنْ سَلَكَ طَرِيقًا يَلْتَمِسُ فِيهِ عِلْمًا سَهَّلَ اللَّهُ لَهُ بِهِ طَرِيقًا إِلَى الْجَنَّةِ وَمَا اجْتَمَعَ قَوْمٌ فِي بَيْتٍ مِنْ بُيُوتِ اللَّهِ يَتْلُونَ كِتَابَ اللَّهِ وَيَتَدَارَسُونَهُ بَيْنَهُمْ إِلاَّ حَفَّتْهُمُ الْمَلاَئِكَةُ وَنَزَلَتْ عَلَيْهِمُ السَّكِينَةُ وَغَشِيَتْهُمُ الرَّحْمَةُ وَذَكَرَهُمُ اللَّهُ فِيمَنْ عِنْدَهُ وَمَنْ أَبْطَأَ بِهِ عَمَلُهُ لَمْ يُسْرِعْ بِهِ نَسَبُهُ ‏"‏ ‏.‏
