Hadith 246
Abu Musa Al-Ash'ari (May Allah be pleased with him) reported:
وعن أبي موسى الأشعري رضي الله عنه قال: كان النبي صلى الله عليه وسلم إذا أتاه طالب حاجة أقبل على جلسائه فقال: :اشفعوا تؤجروا ويقضي الله على لسان نبيه ما أحب" ((متفق عليه)). (16)
Whenever a needy person would come to the Prophet (ﷺ), he would turn to those who were present and say, "If you make intercession for him, you will be rewarded, because Allah decreed what He likes by the tongue of His Messenger". [Al-Bukhari and Muslim].
In plain words
Whenever someone came with a need, the Prophet would invite those present to speak up for that person, telling them they would be rewarded for interceding. Helping carry another's request is itself an act of good.
