Nadr b. Anas reported, as when Anas was alive, that he said:
حَدَّثَنِي حَامِدُ بْنُ عُمَرَ ، حَدَّثَنَا عَبْدُ الْوَاحِدِ ، حَدَّثَنَا عَاصِمٌ ، عَنِ النَّضْرِ بْنِ أَنَسٍ ، وَأَنَسٌ، يَوْمَئِذٍ حَىٌّ قَالَ أَنَسٌ لَوْلاَ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ يَتَمَنَّيَنَّ أَحَدُكُمُ الْمَوْتَ " . لَتَمَنَّيْتُهُ .
Had Allah's Messenger (ﷺ) not stated this.." None should make a request for death," I would have definitely done that.
