The Messenger of Allah ﷺ said, "What Allah has permitted in His Book is lawful, what He has forbidden is unlawful, and what He has remained silent about is a pardon. So accept from Allah His pardon, for Allah does not forget." Then he recited this verse, "And your Lord is never forgetful" [Maryam 19:64].
قال رسول الله ﷺ: ما أحل الله في كتابه فهو حلال، وما حرم فهو حرام، وما سكت عنه فهو عافية، فاقبلوا من الله عافيته، فإن الله لم يكن نسيا، ثم تلا هذه الآية {وما كان ربك نسيا}

Bazzar said, "Its isnad is sound." Hakim said, "sahih in isnad." Haythami said in al-Majmu (1/171), "Its isnad is hasan, and its narrators are trustworthy."
