Abu Sa’id Al Khudri said “The Apostle of Allaah ﷺ sent an expedition towards Banu Lihyan and said “One of the two persons should go forth. He then said to those who sat (at home), If any one of you looks after the family and property of a warrior, he will receive half the reward of the one who goes forth (in jihad).” (Using translation from Abū Dāʾūd 2510)
أَنَّ النَّبِيَّ ﷺ بَعَثَ بَعْثًا إِلَى بَنِي لِحْيَانَ قَالَ يَعْنِي لِيَنْبَعِثْ مِنْ كُلِّ رَجُلَيْنِ رَجُلٌ وَقَالَ لِلْقَاعِدِ أَيُّكُمَا خَلَفَ الْخَارِجَ فِي أَهْلِهِ وَمَالِهِ بِخَيْرٍ كَانَ لَهُ مِثْلُ نِصْفِ أَجْرِ الْخَارِجِ
