Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates: He heard the Prophet Muhammad (peace and blessings be upon him) saying: "When you hear the muezzin, say the same words as he says. Then send blessings upon me, for whoever sends blessings upon me once, Allah will send ten mercies upon him. Then ask Allah to grant me al-Wasilah, which is a rank in Paradise that 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."
