Q: If any difficulties come in life, is that because of our deeds (amal)?
A: Generally it is because of our a`maal and there may be other reasons as well for difficulties coming our way. It does not always have to be due to our a`maal.
And Allah Ta’ala (الله تعالى) knows best.
ظَهَرَ الفَسادُ فِى البَرِّ وَالبَحرِ بِما كَسَبَت أَيدِى النّاسِ لِيُذيقَهُم بَعضَ الَّذى عَمِلوا لَعَلَّهُم يَرجِعونَ ﴿الروم:٤١﴾
