Hadith Sixteen: From Abdullah bin Amr bin al-Aas (Allah be pleased with them both) said: I heard the Messenger of Allah (Allah bless him and give him peace) say: If you hear the caller to prayer, then repeat what he says, then send blessings upon me, for he who sends a single blessing upon me, Allah sends ten blessings upon him. Then ask Allah (the most High) for wasilah for me, for it is a station in paradise which is not for except a servant from the servants of Allah (the most High). I hope that I am him, for whoever asks Allah (the most High) for wasilah for me my intercession becomes permissible for him.
Reported by Muslim in his Sahih
And in a wording: If you hear the caller to prayer call, then repeat what he says and then send blessings upon me, for no one sends a single blessing upon me except that Allah sends ten blessings upon him. And ask for me al-Wasilah, for al-Wasilah is a station in paradise which is not except for a servant from the servants of Allah, and I hope that I am him. And he who asks for it for me, my intercession becomes permissible for him on the day of judgement.
It was mentioned by al-Hafidh Rashid al-Din who said: The hadith is Hasan Sahih
Hadith Seventeen: From Abdullah bin Umar (Allah be pleased with both of them) said: The Messenger of Allah (Allah bless him and give him peace) said: Whoever sends blessings upon me, or asks Allah (the most High) for al-Wasilah for me, has a right to my intercession on the day of judgement.

Hadith Eighteen: From Abdullah bin Masud (Allah be pleased with him) said: The Messenger of Allah (Allah bless him and give him peace) said: There is no Muslim who repeats when he hears the call to prayer, makes takbir, and bears witness that there is no god except Allah, and bears witness that Muhammad is the Messenger of Allah and then says: O Allah, bestow on Muhammad al-Wasilah and virtue (fadilah), and make his rank amongst the highest, and his love amongst the chosen ones, and his remembrance amongst the ones who are drawn near, except that intercession is compulsory for him on the day of judgement.

Hadith Nineteen: From Abdullah bin Abbas (Allah be pleased with both of them) said: The Messenger of Allah (Allah bless him and give him peace) said: Ask Allah for al-Wasilah for me, for no Muslim or believer asks it for me except that I will be a witness or intercessor for him.

Reported by al-Bukhari, Imam Ahmad, Abu Dawud, Ibn Majah and al-Tirmidhi who said: the hadith is Hasan Gharib
And in a wording: he has a right to my intercession
And in a wording: al-Wasilah is a rank with Allah (the most High) above which there is no other rank, so ask Allah (the most High) to grant me al-Wasilah over His creation.
Reported by Ismaeel al-Qadi with a Hasan chain
And in a wording: Send blessings upon me, for your sending blessings upon me is a zakat for you, and ask Allah for al-Wasilah for me. He said: either he told us or we asked him.
He said: al-Wasilah is the highest rank in paradise which no one will obtain except one person, and I hope to be that person.
