The word(s) "decisive" appears 5 time(s) in 5 verse(s) in Quran in Muhammad Pickthal translation.

(1) Thus have We revealed it, a decisive utterance in Arabic; and if thou shouldst follow their desires after that which hath come unto thee of knowledge, then truly wouldst thou have from Allah no protecting friend nor defender.

(2) We made his kingdom strong and gave him wisdom and decisive speech.

(3) Or have they partners (of Allah) who have made lawful for them in religion that which Allah allowed not? And but for a decisive word (gone forth already), it would have been judged between them. Lo! for wrong-doers is a painful doom.

(4) And Lo! in the Source of Decrees, which We possess, it is indeed sublime, decisive.

(5) And those who believe say: If only a surah were revealed! But when a decisive surah is revealed and war is mentioned therein, thou seest those in whose hearts is a disease looking at thee with the look of men fainting unto death. Therefor woe unto them!
