إِنَّ هَٰٓؤُلَآءِ لَيَقُولُونَ
Surah Ad-Dukhaan(44:34)
Sahih al-Bukhari
Fighting for the Cause of Allah (Jihaad)
Chapter: If a man has enlisted himself in the army and then his wife goes out for Hajj
Narrated Ibn `Abbas:
That he heard the Prophet (ﷺ) saying, "It is not permissible for a man to be alone with a woman, and no lady should travel except with a Muhram (i.e. her husband or a person whom she cannot marry in any case for ever; e.g. her father, brother, etc.)." Then a man got up and said, "O Allah's Messenger (ﷺ)! I have enlisted in the army for such-and-such Ghazwa and my wife is proceeding for Hajj." Allah's Messenger (ﷺ) said, "Go, and perform the Hajj with your wife."
