Yahya: On the authority of Abd al-Aziz ibn Abi Rawwad; that the Messenger of Allah, peace be upon him, said: "Seek wealth in this verse: 'If they should be poor, Allah will enrich them from His bounty.'"
Yahya: On the authority of Sa'id, from Qatada; that Umar ibn al-Khattab used to say: "I have never seen the likes of a man who does not seek wealth in marriage, while Allah says: 'If they should be poor, Allah will enrich them..."
﴿وَأنْكحُوا الْأَيَامَى مِنْكُم﴾ يَعْنِي: كُلَّ امْرَأَةٍ لَيْسَ لَهَا زَوْجٌ.

(يَحْيَى: عَنْ عَبْدِ الْعَزِيزِ بْنِ أَبِي رَوَّادٍ؛ أَنَّ رَسُولَ اللَّهِ عليه السلام قَالَ: " اطْلُبُوا الْغِنَى فِي هَذِهِ الْآيَةِ: ﴿إِنْ يَكُونُوا فُقَرَاءَ يُغْنِهِمُ الله من فَضله﴾ ").
