The Messenger of Allah ﷺ said, "Whoever equips a warrior has himself fought, and whoever takes good care of a warrior's family in his absence has himself fought."
حدثنا عبد الصمد حدثنا حرب حدثنا يحيى حدثني أبو سلمة حدثني بسر بن سعيد حدثني ا
أن رسول الله ﷺ قال من جهز غازيا فقد غزا ومن خلف غازيا في أهله بخير فقد غزا
Its chain of transmission is sahih. Harb is Ibn Maymun al-Akbar, and he is trustworthy, the imams have confirmed his reliability. Yahya is Ibn Saeed Ansari, and Abu Salama is Ibn Abdul-Rahman bin Awf. The hadith was already mentioned at 16993.I say, considerable confusion has arisen among the imams regarding this Harb bin Maymun. Some of them consider them two people, a younger one and an older one. Others consider them one person. They have accused Bukhari of treating them as one person. The editor of Tahzib Kamal went on at length about this matter, faulting many scholars, then faulting the printed edition of Tarikh al-Kabir, claiming that it actually contains two entries and attributing the discrepancy to an old scribal error, on the grounds that those who preceded Mizzi transmitted from Tarikh al-Kabir that it treated them as one person. But the conclusion reached by the researchers is that they are two, without dispute. Ibn Hajar said in Tajil, "He is among those who conflated the two," and what he says is correct.The editor of Tahzib Kamal had no need to involve himself in a struggle with giants. He is eager to do such things, yet I have not seen him succeed in even a single one.
