The word(s) "suffering" appears 5 time(s) in 3 verse(s) in Quran in Mohsin Khan translation.

(1) And don't be weak in the pursuit of the enemy; if you are suffering (hardships) then surely, they (too) are suffering (hardships) as you are suffering, but you have a hope from Allah (for the reward, i.e. Paradise) that for which they hope not; and Allah is Ever All-Knowing, All-Wise.

(2) And We sent no Prophet unto any town (and they denied him), but We seized its people with suffering from extreme poverty (or loss in wealth) and loss of health (and calamities), so that they might humiliate themselves (and repent to Allah).

(3) Except those who believe (in Islamic Monotheism) and do righteous good deeds, and recommend one another to the truth [i.e. order one another to perform all kinds of good deeds (Al-Ma'ruf) which Allah has ordained, and abstain from all kinds of sins and evil deeds (Al-Munkar which Allah has forbidden], and recommend one another to patience (for the sufferings, harms, and injuries which one may encounter in Allah's Cause during preaching His religion of Islamic Monotheism or Jihad).
