Messenger of Allah ﷺ said, " He who pre pares a Ghazi going in Allah's Cause is given a reward equal to that of) a Ghazi; and he who looks after properly the dependents of a Ghazi going in Allah's Cause is (given a reward equal to that of) Ghazi."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ جَهَّزَ غَازِيًا فِي سَبِيلِ اللَّهِ فَقَدْ غَزَا وَمَنْ خَلَفَ غَازِيًا فِي سَبِيلِ اللَّهِ بِخَيْرٍ فَقَدْ غَزَا  

The Prophet ﷺ used not to enter any house in Medina except the house of Um Sulaim besides those of his wives when he was asked why, he said, "I take pity on her as her brother was killed in my company. "  

أَنَّ النَّبِيَّ ﷺ لَمْ يَكُنْ يَدْخُلُ بَيْتًا بِالْمَدِينَةِ غَيْرَ بَيْتِ أُمِّ سُلَيْمٍ إِلاَّ عَلَى أَزْوَاجِهِ فَقِيلَ لَهُ فَقَالَ: «إِنِّي أَرْحَمُهَا قُتِلَ أَخُوهَا مَعِي۔»
