Narrated Zaid bin Khalid Al-Juhani:
That the Messenger of Allah (ﷺ) said, "Whoever prepares a fighter in Allah's cause, he has participated in a military expedition, and whoever looks after the family of a fighter, he has participated in a military expedition." [Abu 'Eisa said:] This Hadith is Hasan Sahih, and it has been reported through more than one route.
حَدَّثَنَا أَبُو زَكَرِيَّا، يَحْيَى بْنُ دُرُسْتَ الْبَصْرِيُّ حَدَّثَنَا أَبُو إِسْمَاعِيلَ، حَدَّثَنَا يَحْيَى بْنُ أَبِي كَثِيرٍ، عَنْ أَبِي سَلَمَةَ، عَنْ بُسْرِ بْنِ سَعِيدٍ، عَنْ زَيْدِ بْنِ خَالِدٍ الْجُهَنِيِّ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ
مَنْ جَهَّزَ غَازِيًا فِي سَبِيلِ اللَّهِ فَقَدْ غَزَا وَمَنْ خَلَفَ غَازِيًا فِي أَهْلِهِ فَقَدْ غَزَا
. قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ وَقَدْ رُوِيَ مِنْ غَيْرِ هَذَا الْوَجْهِ .
