Mishkat al-Masabih 4 Prayer كتاب الصلاة 658

وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «خُذُوا مِنَ الْأَعْمَالِ مَا تُطِيقُونَ فَإِنَّ اللَّهَ لَا يمل حَتَّى تملوا»

She reported God’s Messenger as saying; “Choose such actions as you are capable of performing, for God does not grow weary till you do.” (Bukhari and Muslim.)
