It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever sends blessings upon me, his blessing reaches me, and I send mercy upon him, and besides that, ten good deeds are written for him."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated these two hadiths from Abu Ja'far (may Allah have mercy on him) except Muhammad bin Sulayman (may Allah have mercy on him)."
