Fighting for the Cause of Allah (Jihaad)
To give a Bai'a for not to flee during a battle
حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، سَمِعَ مُحَمَّدَ بْنَ فُضَيْلٍ، عَنْ عَاصِمٍ، عَنْ أَبِي عُثْمَانَ، عَنْ مُجَاشِعٍ ـ رضى الله عنه ـ قَالَ أَتَيْتُ النَّبِيَّ صلى الله عليه وسلم أَنَا وَأَخِي فَقُلْتُ بَايِعْنَا عَلَى الْهِجْرَةِ. فَقَالَ " مَضَتِ الْهِجْرَةُ لأَهْلِهَا ". فَقُلْتُ عَلاَمَ تُبَايِعُنَا قَالَ " عَلَى الإِسْلاَمِ وَالْجِهَادِ ".
Narrated Mujashi: My brother and I came to the Prophet (ﷺ) and I requested him to take the pledge of allegiance from us for migration. He said, "Migration has passed away with its people." I asked, "For what will you take the pledge of allegiance from us then?" He said, "I will take (the pledge) for Islam and Jihad."
