Ayesha reported,

We had a mat that we would spread out during the day and use as a partition at night. Something escaped me that I did not catch from Sufyan, that the Messenger of Allah ﷺ said, the Muslims were praying along with his prayer, so he said, "Take on of deeds what you can sustain, for Allah does not tire until you tire." When he performed a prayer, he kept it up consistently, and the deeds he loved most were those done most regularly.

حدثنا سفيان عن ابن عجلان عن سعيد عن أبي سلمة

عن عائشة قالت

كانت لنا حصيرة نبسطها بالنهار ونتحجرها بالليل خفي علي شيء لم أفهمه من سفيان أن رسول الله ﷺ قال المسلمون يصلون بصلاته فقال اكلفوا من العمل ما تطيقون فإن الله عز وجل لا يمل حتى تملوا وكان إذا صلى صلاة أثبتها وكان أحب العمل إليه أدومه
