Abu Huraira reported God's Messenger as saying, “How excellent it is for a slave to be taken in death by God when worshipping his Lord well and obeying his master! How excellent it is for him!” (Bukhari and Muslim.)
وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «نِعِمَّا لِلْمَمْلُوكِ أَنْ يَتَوَفَّاهُ اللَّهُ بِحُسْنِ عِبَادَةِ رَبِّهِ وَطَاعَة سَيّده نعما لَهُ»
