Abu Huraira reported God’s Messenger as saying, “I was shown the first three to enter paradise:

a martyr, a continent man who refrains from what is unlawful, and a slave who worships God well and serves his patrons sincerely." Tirmidhi transmitted it.

وَعَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ:

عَرَضَ عَلَيَّ أَوَّلُ ثَلَاثَةٍ يَدْخُلُونَ الْجَنَّةَ: شَهِيدٌ وَعَفِيفٌ مُتَعَفِّفٌ وَعَبَدٌ أَحْسَنَ عبادةَ اللَّهِ ونصح لمواليه
