Make a pledge (bay'at)

Bismillah.

O son, be sure to make effort to be near with the solehin as in the du'a mentioned in the Qur'an:
‘My Lord, inspire me to be thankful for Your grace with which You have favoured me and my parents, and to do good that will please You, and include me, by Your mercy, among Your righteous servants’, the prophets and saints.
(Qur'an, An-Naml,19)
And please by all means, do make a pledge with the saints. Making a pledge with one of them is like making a pledge with Allah. This is our way. This is the way of your forefathers. So listen to me!

إِنَّ ٱلَّذِينَ يُبَايِعُونَكَ إِنَّمَا يُبَايِعُونَ ٱللَّهَ يَدُ ٱللَّهِ فَوْقَ أَيْدِيهِمْ فَمَن نَّكَثَ فَإِنَّمَا يَنكُثُ عَلَىٰ نَفْسِهِ وَمَنْ أَوْفَىٰ بِمَا عَاهَدَ عَلَيْهُ ٱللَّهَ فَسَيُؤْتِيهِ أَجْراً عَظِيماً
"Those who pledge allegiance with you (by placing their hands in your hand) they, in fact, pledge allegiance with Allah. Allah’s hand is over their hands. Then, whoever breaks his pledge breaks it to his own detriment, and whoever fulfills the covenant he has made with Allah, He will give him a great reward." (Qur'an, Al-Fath,10)
Sadaqallah al-Azim. Allah says the truth!
