Hadith 10:18
‘A’isha reported the Prophet as saying, “The marriage which produces most blessing is that which involves least burden.” Baihaqi transmitted in Shu'ab al-iman .
وَعَن عَائِشَةَ قَالَتْ: قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ أَعْظَمَ النِّكَاحِ بَرَكَةً أَيْسَرُهُ مُؤْنَةً» . رَوَاهُمَا الْبَيْهَقِيّ فِي شعب الْإِيمَان
