The recommendation to make du‘ā’ for a person who offers one wealth or something else

WE RELATE IN the Ṣaḥīḥ of al-Bukhārī and elsewhere that Anas related that when ‘Abd ar-Raḥmān ibn ‘Awf came to Madīnah he lodged with Sa‘d ibn Rabī‘ . [Sa‘d ibn Rabī‘] said to him: “I will divide my wealth with you and divorce one of my wives for you.” He replied: “May Allah bless you in your family and wealth.”
