وَلِأَحْمَدَ, وَأَبِي دَاوُدَ: مِنْ حَدِيثِ أَبِي سَعِيدٍ نَحْوُهُ, وَزَادَ: { اِرْجِعْ فَاسْتَأْذِنْهُمَا, فَإِنْ أَذِنَا لَكَ; وَإِلَّا فَبِرَّهُمَا } [1] .
Ahmad and Abu Dawud transmitted a similar hadith on the authority of Abu Sa’id, and they added the extra statement, “Go back and ask for their permission. If they permit you to go, then go for Jihad otherwise, be good to them (look after them).
