Riyad as-Salihin — Hadith #46201

On the authority of Abdullah bin Amr bin Al-Aas, may God be pleased with them both, that he heard the Messenger of God, may God bless him and grant him peace, say: “If you hear the call, say the same as what he says, then pray for me, for whoever prays a prayer, God will bless him ten times, then ask God for the wasila for me, for it is a position in Paradise that is only befitting for a servant of God, and I hope that I am him, so whoever asks for the wasila for me, intercession is permissible for him” ((Narrated by Muslim)).
