It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When it is Friday, send abundant blessings (salat) upon me, for your blessings are presented to me; and ask (Allah) for al-Wasilah for me." The Companions (may Allah be pleased with them) said: "O Messenger of Allah, what is al-Wasilah?" He (peace and blessings be upon him) said: "The highest rank in Paradise, with me."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Muhammad bin Amr except al-Qasim bin Ghusn; Muhammad bin Abd al-Aziz is alone in narrating it."
