The word(s) "say" appears 931 time(s) in 776 verse(s) in Quran in Mohsin Khan translation.

(251) And when We let mankind taste mercy after some adversity has afflicted them, behold! they take to plotting against Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.)! say: "Allah is more Swift in planning!" Certainly, Our Messengers (angels) record all of that which you plot.

(252) He it is Who enables you to travel through land and sea, till when you are in the ships, and they sail with them with a favourable wind, and they are glad therein, then comes a stormy wind and the waves come to them from all sides, and they think that they are encircled therein. Then they invoke Allah, making their Faith pure for Him Alone, (saying): "If You (Allah) deliver us from this, we shall truly be of the grateful."

(253) And the Day whereon We shall gather them all together, then We shall say to those who did set partners in worship with Us: "Stop at your place! You and your partners (whom you had worshipped in the worldly life)." then We shall separate them, and their (Allah's so-called) partners shall say: "It was not us that you used to worship."

(254) say (O Muhammad صلى الله عليه وسلم): "Who provides for you from the sky and the earth? Or who owns hearing and sight? And who brings out the living from the dead and brings out the dead from the living? And who disposes the affairs?" They will say: "Allah." say: "Will you not then be afraid of Allah's punishment (for setting up rivals in worship with Allah)?"

(255) say: "Is there of your (Allah's called) partners one that originates the creation and then repeats it?" say: "Allah originates the creation and then He repeats it. Then how are you deluded away (from the truth)?"

(256) say: "Is there of your (Allah's so-called) partners one that guides to the truth?" say: "It is Allah Who guides to the truth. Is then He Who guides to the truth more worthy to be followed, or he who finds not guidance (himself) unless he is guided? Then, what is the matter with you? How judge you?"

(257) Or do they say: "He (Muhammad صلى الله عليه وسلم) has forged it?" say: "Bring then a Surah (chapter) like unto it, and call upon whomsoever you can besides Allah, if you are truthful!"

(258) And if they belie you, say: "For me are my deeds and for you are your deeds! You are innocent of what I do, and I am innocent of what you do!"

(259) And they say: "When will be this promise (the torment or the Day of Resurrection), if you speak the truth?"

(260) say (O Muhammad صلى الله عليه وسلم): "I have no power over any harm or profit to myself except what Allah may will. For every Ummah (a community or a nation), there is a term appointed; when their term comes, neither can they delay it nor can they advance it an hour (or a moment)." (Tafsir Al-Qurtubi).
