Man prays for evil as (or when) he prays for good (or he makes his prayer evil or prays for evil when it should be for good); for man was ever hasty (or impatient or superficial)
And man invokes (Allah) for evil as he invokes (Allah) for good and man is ever hasty (i.e., if he is angry with somebody, he invokes (saying): "O Allah! Curse him, etc." and that one should not do, but one should be patient)
Man invites his evil as eagerly as he invites his good! Man is indeed hasty!
Sayyed Abbas Sadr-Ameli
And man prays for evil as he prays for the good; and man is ever hasty.
Al-muntakhab fi tafsir al-Qur'an al-Karim
Man moves quickly and sometimes unjustly (as in response to slander) to invoke evil upon people as he moves quickly to invoke a blessing upon them, for man has a natural propensity in him to be unduly hasty of spirit
