عَنْ أَبِي مُوسَى الْأَشْعَرِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ كُنَّا جُلُوسًا عِنْدَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ وَإِنَّهُ سَأَلَهُ سَائِلٌ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ اشْفَعُوا تُؤْجَرُوا وَلْيَقْضِ اللَّهُ عَزَّ وَجَلَّ عَلَى لِسَانِ نَبِيِّهِ مَا أَحَبَّ
It is narrated from Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him), he says: We were sitting with the Noble Prophet (peace and blessings be upon him) when a beggar asked a question. The Prophet (peace and blessings be upon him) said: Intercede, you will be rewarded, and Allah Almighty decrees what He wills through the tongue of His Prophet.
