From the route of Abu Hurayrah, may Allah accept his deeds, who said: the Messenger of Allah, sallallahu ^alayhi wa sallam, said in Hadith Qudsiyy:
<< Allah , the exalted, said: ‘The one who declares enmity upon one of My Waliyys ( highly pious slaves) then let him know that he is declaring war against Me. The one of My slaves will not be able to be closely obedient to Me, in a matter more accepted to Me, than what I had decreed to be obligatory upon him.
‘My slave will be diligently engaged in supererogatory acts of worship until I accept him, and if I accept him I will grant him special powers in the hearing with which he hears, the sight with which he sees, the hand with which he touches, the foot with which he walks, and if he asks Me for something I will answer him and if he seeks refuge with Me I will protect him.’>>
