Husband and wife should have the same religion
حَدَّثَنَا عُبَيْدُ بْنُ إِسْمَاعِيلَ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ دَخَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم عَلَى ضُبَاعَةَ بِنْتِ الزُّبَيْرِ فَقَالَ لَهَا " لَعَلَّكِ أَرَدْتِ الْحَجَّ ". قَالَتْ وَاللَّهِ لاَ أَجِدُنِي إِلاَّ وَجِعَةً. فَقَالَ لَهَا " حُجِّي وَاشْتَرِطِي، قُولِي اللَّهُمَّ مَحِلِّي حَيْثُ حَبَسْتَنِي ". وَكَانَتْ تَحْتَ الْمِقْدَادِ بْنِ الأَسْوَدِ.
Narrated `Aisha: Allah's Messenger (ﷺ) entered upon Dubaa bint Az-Zubair and said to her, "Do you have a desire to perform the Hajj?" She replied, "By Allah, I feel sick." He said to her, "Intend to perform Hajj and stipulate something by saying, 'O Allah, I will finish my Ihram at any place where You stop me (i.e. I am unable to go further)." She was the wife of Al-Miqdad bin Al-Aswad.
