Can a Muslim be rewarded for occurrences in life that are normal but minor inconveniences? For example he hurts his foot against a door, or breaks a glass, or misses something important, but he does not get upset and says الحمدلله. What does the Quran and Sunnah say about such? Barakallahu feekum.

Ustadh AbdulAziz al-Haqqan

Yes you are correct. Allah's Messenger (ﷺ) said: There is no trouble that comes to a believer except that it obliterates from his sins, even if it is the pricking of a thorn. (Sahih Muslim).
