Ill Thought (Hadith No. 935)


Assalamu`alaykum,
Bismillah.

Volume 2, Book 21, Number 236:
Narrated Abu-Wa'il:
'Abdullah said, "One night I offered the Tahajjud prayer with the Prophet and he kept on standing till an ill-thought came to me." We said, "What was the ill-thought?" He said, "It was to sit down and leave the Prophet (standing)."

We can so relate to this, no? Especially with Ramadan coming up. Think of the long taraweeh qiyaam. What comes to your mind? (Pause and think!)
And then imagine... why didn't such ill thoughts come to Prophet (SAW)'s mind? Why did he love to pray for long hours? His feet would swell and all he would say was "shall I not be a thankful slave?". :(
Wassalam.
