Of course Allah test us which of one of us good in patient & deeds. Quran says apart from saying He is merciful, it even say there is test. so no wonder why people get handicap children.
Surah Nisa, chapter 4 verse 25 and Surah Maidah, chapter 5 verse 74:
"And Allah is Oft-Forgiving, Most Merciful."
The life in this world is a test for the Hereafter. The Qur’an says in Surah Al Mulk: "He who created Death and Life, that He may try which of you is best in deed; and He is the Exalted in Might, Oft-Forgiving".
[Al-Qur’an 67:2]
IF Allah is so forgiving , why did he create Death ?
he should not have created death so he can be truely forgiving to the living beings who suffer from death
