A man emigrated to the Messenger of Allah ﷺ from the Yemen. He asked (him): Have you anyone (of your relatives) in the Yemen? He replied: My parents. He asked: Did they permit you? He replied: No. He said: Go back to them and ask for their permission. If they permit you, then fight (in the path of Allah), otherwise be devoted to them.
أَنَّ رَجُلاً هَاجَرَ إِلَى رَسُولِ اللَّهِ ﷺ مِنَ الْيَمَنِ فَقَالَ هَلْ لَكَ أَحَدٌ بِالْيَمَنِ قَالَ أَبَوَاىَ قَالَ أَذِنَا لَكَ قَالَ لاَ قَالَ ارْجِعْ إِلَيْهِمَا فَاسْتَأْذِنْهُمَا فَإِنْ أَذِنَا لَكَ فَجَاهِدْ وَإِلاَّ فَبِرَّهُمَا
