عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((مَثَلُ الْمُؤْمِنِ وَمَثَلُ الْإِيمَانِ كَمَثَلِ الْفَرَسِ فِي آخِيَّتِهِ، يَجُولُ ثُمَّ يَرْجِعُ إِلَى آخِيَّتِهِ وَإِنَّ الْمُؤْمِنَ يَسْهُو ثُمَّ يَرْجِعُ إِلَى الْإِيمَانِ فَأَطْعِمُوا طَعَامَكُمْ الْأَتْقِيَاءَ وَأَوْلُوا مَعْرُوفَكُمْ الْمُؤْمِنِينَ))
It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: The example of a believer and faith is like that of a horse tied to its stake; it wanders around here and there but returns and stands by the stake. Similarly, a believer may forget, but then he returns to faith. You should feed the righteous and bestow all kinds of goodness upon the people of faith.
