﴿ وَلَا تُصَلِّ عَلَىٰٓ أَحَدٍۢ مِّنْهُم مَّاتَ أَبَدًۭا وَلَا تَقُمْ عَلَىٰ قَبْرِهِۦٓ ۖ إِنَّهُمْ كَفَرُوا۟ بِٱللَّهِ وَرَسُولِهِۦ وَمَاتُوا۟ وَهُمْ فَٰسِقُونَ ﴾

“And never shalt thou pray over any of them that has died, and never shalt thou stand by his grave: for, behold, they were bent on denying God and His Apostle, and they died in this their iniquity.”

(And never (O Muhammad) pray for one of them who dieth) i.e. any of the hypocrites after the death of 'Abdullah Ibn Ubayy, (nor stand by his grave. Lo! they disbelieved in Allah and His messenger) in secret, (and they died while they were evil-doers) hypocrites.
