Messenger of Allah ﷺ said, "Allah guarantees him who strives in His Cause and whose motivation for going out is nothing but Jihad in His Cause and belief in His Word, that He will admit him into Paradise (if martyred) or bring him back to his dwelling place, whence he has come out, with what he gains of reward and booty." (Using translation from Bukhārī 3123)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «تَكَفَّلَ اللهُ لِمَنْ جَاهَدَ فِي سَبِيلِهِ لَا يُخْرِجُهُ مِنْ بَيْتِهِ إِلَّا الْجِهَادُ فِي سَبِيلِهِ وَتَصْدِيقُ كَلِمَتِهِ بِأَنْ يُدْخِلَهُ الْجَنَّةَ أَوْ يَرُدَّهُ إِلَى مَسْكَنِهِ الَّذِي خَرَجَ مِنْهُ مَعَ مَا نَالَ مِنْ أَجْرٍ أَوْ غَنِيمَةٍ»
