Narrated 'Abdullah bin 'Amrؓ: that the Messenger of Allahﷺ said: "If you hear the Muadh-dhin then say as he says. Then send Salat upon me, because whoever sends Salat upon me, Allahﷻ will send Salat upon him ten times due to it. Then ask Allahﷻ that He gives me Al-Wasilah, because it is a place in Paradise which is not for anyone except for a slave from the slaves of Allahﷻ, and I hope that I am him. And whoever asks that I have Al-Wasilah, then (my) intercession will be made lawful for him." - Tirmidhi 3614
