Hadith: Whoever relieves a believer from one of the hardships of this world, Allah will relieve him from one of the hardships of the Day of Judgment

عَنْ أَبِي هُرَيْرَةَ رضي الله عنه قَالَ: قَالَ رَسُولُ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ:
«مَنْ نَفَّسَ عَنْ مُؤْمِنٍ كُرْبَةً مِنْ كُرَبِ الدُّنْيَا نَفَّسَ اللهُ عَنْهُ كُرْبَةً مِنْ كُرَبِ يَوْمِ الْقِيَامَةِ، وَمَنْ يَسَّرَ عَلَى مُعْسِرٍ يَسَّرَ اللهُ عَلَيْهِ فِي الدُّنْيَا وَالْآخِرَةِ، وَمَنْ سَتَرَ مُسْلِمًا سَتَرَهُ اللهُ فِي الدُّنْيَا وَالْآخِرَةِ، وَاللهُ فِي عَوْنِ الْعَبْدِ مَا كَانَ الْعَبْدُ فِي عَوْنِ أَخِيهِ، وَمَنْ سَلَكَ طَرِيقًا يَلْتَمِسُ فِيهِ عِلْمًا سَهَّلَ اللهُ لَهُ بِهِ طَرِيقًا إِلَى الْجَنَّةِ، وَمَا اجْتَمَعَ قَوْمٌ فِي بَيْتٍ مِنْ بُيُوتِ اللهِ يَتْلُونَ كِتَابَ اللهِ وَيَتَدَارَسُونَهُ بَيْنَهُمْ إِلَّا نَزَلَتْ عَلَيْهِمِ السَّكِينَةُ، وَغَشِيَتْهُمُ الرَّحْمَةُ، وَحَفَّتْهُمُ الْمَلَائِكَةُ، وَذَكَرَهُمُ اللهُ فِيمَنْ عِنْدَهُ، وَمَنْ بَطَّأَ بِهِ عَمَلُهُ لَمْ يُسْرِعْ بِهِ نَسَبُهُ».
[صحيح] - [رواه مسلم] - [صحيح مسلم: 2699]

Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said:
"Whoever relieves a believer from one of the hardships of this world, Allah will relieve him from one of the hardships of the Day of Judgment. Whoever makes things easy for someone in difficulty, Allah will make things easy for him in this world and the Hereafter. Whoever covers a Muslim, Allah will cover him in this world and the Hereafter. Allah is in the aid of the slave as long as the slave is in the aid of his brother. Whoever treads a path seeking knowledge, Allah will make easy for him a path to Paradise. No group of people gather in one of the houses of Allah, reciting the Book of Allah and studying it among themselves, except that tranquility descends upon them, mercy envelops them, the angels surround them, and Allah mentions them to those near Him. And whoever is slowed down by his deeds will not be hastened forward by his lineage."
[Authentic hadith] - [Narrated by Muslim] - [Sahih Muslim - 2699]

Explanation

The Prophet (may Allah's peace and blessings be upon him) clarified that the reward a Muslim receives from Allah is of the same nature as the actions he performs for other Muslims. Whoever relieves, alleviates, removes, or eliminates a hardship and a difficulty from a believer in this world, Allah will reward him by relieving him from one of the hardships of the Day of Judgment. And whoever facilitates and makes things easy for someone in difficulty and removes his difficulty, Allah will make it easy for him in this world and the Hereafter. And whoever conceals the faults of a Muslim, such as knowing what should not be exposed of slips and errors, Allah will conceal his faults in this world and the Hereafter. Allah supports His slave as long as the slave supports his brother in his religious and worldly interests. Support could be through supplication, physical action, money, etc. Whoever walks in pursuit of religious knowledge, doing it for the sake of Allah Almighty, Allah will facilitate for him a path to Paradise. No group of people gather in one of the houses of Allah, reciting the Book of Allah and studying it among themselves, except that tranquility and solemnity descend upon them, the mercy of Allah envelops and encompasses them, the angels surround them, and Allah praises them in the presence of those near Him. It is enough of an honor that Allah mentions the slave in the highest assembly. The one whose good deeds are insufficient will not be elevated to the rank of those with righteous deeds. Hence, he should not rely upon his noble lineage and the merit of his forefathers while neglecting the performance of good deeds.
