Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates: He heard the Prophet (peace and blessings of Allah be upon him) saying: "When you hear the muezzin, say the same words as he says, and send blessings upon me, for whoever sends blessings upon me once, Allah sends mercy upon him ten times. Then ask Allah to grant me al-Wasilah, for it is a rank in Paradise which will be given to only one of Allah’s servants, and I hope that I will be that servant. Whoever asks Allah for al-Wasilah for me, my intercession will become obligatory for him."
