Do not take on more than you can hold
He told them Allah does not tire of rewarding, but they would tire of doing.
إِنَّكُمْ لَسْتُمْ فِي ذَلِكَ مِثْلِي إِنِّي أَبِيتُ يُطْعِمُنِي رَبِّي وَيَسْقِينِي فَاكْلَفُوا مِنَ الأَعْمَالِ مَا تُطِيقُونَ
Take on of deeds what you can manage.
The full narration
Abu Huraira (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying:Abstain from Saum-Wisal. They (his Companions) said: Messenger of Allah, but you observe Saum Wisal. Upon this he said: You are not like me in this matter, for I spend my night (in a state) that my Lord feeds me and provides me drink Devote yourselves to the deeds (the burden of which) you can bear
