Hadith 1691
Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said: "When you hear the muezzin, then say the same words as he says, and then send blessings upon me. Whoever sends blessings upon me once, Allah bestows ten mercies upon him, and ask Allah to grant me al-Wasilah, for al-Wasilah 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 al-Wasilah for me, my intercession will be obligatory for him on the Day of Resurrection."
