Husband and wife should have the same religion

Narrated 'Aisha:

Abu Hudhaifa bin 'Utba bin Rabi'a bin Abdi Shams who had witnessed the battle of Badr along with the Prophet adopted Salim as his son, to whom he married his niece, Hind bint Al-Walid bin 'Utba bin Rabi'a;
and Salim was the freed slave of an Ansar woman, just as the Prophet had adopted Zaid as his son. It was the custom in the Pre-lslamic Period that if somebody adopted a boy, the people would call him the son of the adoptive father and he would be the latter's heir. But when Allah revealed the Divine Verses: 'Call them by (the names of) their fathers . . . your freed-slaves,' (33.5) the adopted persons were called by their fathers' names. The one whose father was not known, would be regarded as a Maula and your brother in religion. Later on Sahla bint Suhail bin 'Amr Al-Quraishi Al-'Amiri--and she was the wife of Abu- Hudhaifa bin 'Utba--came to the Prophet and said, "O Allah's Apostle! We used to consider Salim as our (adopted) son, and now Allah has revealed what you know (regarding adopted sons)." The sub-narrator then mentioned the rest of the narration.

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي عُرْوَةُ بْنُ الزُّبَيْرِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ أَنَّ أَبَا حُذَيْفَةَ بْنَ عُتْبَةَ بْنِ رَبِيعَةَ بْنِ عَبْدِ شَمْسٍ،، وَكَانَ، مِمَّنْ شَهِدَ بَدْرًا مَعَ النَّبِيِّ ﷺ تَبَنَّى سَالِمًا، وَأَنْكَحَهُ بِنْتَ أَخِيهِ هِنْدَ بِنْتَ الْوَلِيدِ بْنِ عُتْبَةَ بْنِ رَبِيعَةَ وَهْوَ مَوْلًى لاِمْرَأَةٍ مِنَ الأَنْصَارِ، كَمَا تَبَنَّى النَّبِيُّ ﷺ زَيْدًا، وَكَانَ مَنْ تَبَنَّى رَجُلاً فِي الْجَاهِلِيَّةِ دَعَاهُ النَّاسُ إِلَيْهِ وَوَرِثَ مِنْ مِيرَاثِهِ حَتَّى أَنْزَلَ اللَّهُ {ادْعُوهُمْ لآبَائِهِمْ} إِلَى قَوْلِهِ {وَمَوَالِيكُمْ} فَرُدُّوا إِلَى آبَائِهِمْ، فَمَنْ لَمْ يُعْلَمْ لَهُ أَبٌ كَانَ مَوْلًى وَأَخًا فِي الدِّينِ، فَجَاءَتْ سَهْلَةُ بِنْتُ سُهَيْلِ بْنِ عَمْرٍو الْقُرَشِيِّ ثُمَّ الْعَامِرِيِّ ـ وَهْىَ امْرَأَةُ أَبِي حُذَيْفَةَ ـ النَّبِيَّ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّا كُنَّا نَرَى سَالِمًا وَلَدًا وَقَدْ أَنْزَلَ اللَّهُ فِيهِ مَا قَدْ عَلِمْتَ فَذَكَرَ الْحَدِيثَ.

Narrated 'Aisha:

Allah's Apostle 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.

حَدَّثَنَا عُبَيْدُ بْنُ إِسْمَاعِيلَ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ دَخَلَ رَسُولُ اللَّهِ ﷺ 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 Abu Huraira:

The Prophet ﷺ said, "A woman is married for four things, i.e., her wealth, her family status, her beauty and her religion. So you should marry the religious woman (otherwise) you will be a losers.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، قَالَ حَدَّثَنِي سَعِيدُ بْنُ أَبِي سَعِيدٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ ﷺ قَالَ " تُنْكَحُ الْمَرْأَةُ لأَرْبَعٍ لِمَالِهَا وَلِحَسَبِهَا وَجَمَالِهَا وَلِدِينِهَا، فَاظْفَرْ بِذَاتِ الدِّينِ تَرِبَتْ يَدَاكَ ".
