Messenger of Allah ﷺ said, "From among all the conditions which you have to fulfill, the conditions which make it legal for you to have sexual relations (i.e. the marriage contract) have the greatest right to be fulfilled." (Using translation from Bukhārī 2721)
قَالَ رَسُولُ اللهِ ﷺ إِنَّ أَحَقَّ الشُّرُوطِ أَنْ يُوَفَّى بِهِ مَا اسْتَحْلَلْتُمْ بِهِ الْفُرُوجَ
