A mureed relates...
Once I was walking out of the musjid with Sheikh Molouna Ibrahim Mia (Rahmatullah Alayhi). Sheikh was in a hurry to get home (home was a few doors away) as he had a runny tummy.
I told Sheikh (Rahmatullah Alayhi) that his runny tummy was probably the result of something he ate.
Sheikh responded by saying, “Never say such a thing. That is a minor shirk. Everthing is from Allah.”
Lesson: Our Imaan demands that we attribute all good and bad from Allah.
