The word(s) "red" appears 425 time(s) in 377 verse(s) in Quran in Mohsin Khan translation.

(1) But if you do it not, and you can never do it, then fear the Fire (Hell) whose fuel is men and stones, prepared for the disbelievers.

(2) Those who break Allah's Covenant after ratifying it, and sever what Allah has ordered to be joined (as regards Allah's religion of Islamic Monotheism, and to practise its laws on the earth and also as regards keeping good relations with kith and kin ), and do mischief on earth, it is they who are the losers.

(3) O Children of Israel! Remember My Favour which I bestowed upon you and that I preferred you to the 'Alamin [mankind and jinn (of your time period, in the past)].

(4) And (remember) when We delivered you from Fir'aun's (Pharaoh) people, who were afflicting you with a horrible torment, killing your sons and sparing your women, and therein was a mighty trial from your Lord.

(5) And (remember) when We separated the sea for you and saved you and drowned Fir'aun's (Pharaoh) people while you were looking (at them, when the sea-water covered them).

(6) And (remember) when you said, "O Musa (Moses)! We cannot endure one kind of food. So invoke your Lord for us to bring forth for us of what the earth grows, its herbs, its cucumbers, its Fum (wheat or garlic), its lentils and its onions." He said, "Would you exchange that which is better for that which is lower? Go you down to any town and you shall find what you want!" And they were covered with humiliation and misery, and they drew on themselves the Wrath of Allah. That was because they used to disbelieve the Ayat (proofs, evidence, verses, lessons, signs, revelations etc.) of Allah and killed the Prophets wrongfully. That was because they disobeyed and used to transgress the bounds (in their disobedience to Allah, i.e. commit crimes and sins).

(7) He [Musa (Moses)] said, "He says, 'It is a cow neither trained to till the soil nor water the fields, sound, having no other colour except bright yellow.' " They said, "Now you have brought the truth." So they slaughtered it though they were near to not doing it.

(8) And there are among them (Jews) unlettered people, who know not the Book, but they trust upon false desires and they but guess.

(9) And they (Jews) say, "The Fire (i.e. Hell-fire on the Day of Resurrection) shall not touch us but for a few numbered days." Say (O Muhammad صلى الله عليه وسلم to them): "Have you taken a covenant from Allah, so that Allah will not break His Covenant? Or is it that you say of Allah what you know not?"

(10) And (remember) when We took a covenant from the Children of Israel, (saying): Worship none but Allah (Alone) and be dutiful and good to parents, and to kindred, and to orphans and Al-Masakin (the poor), and speak good to people [i.e. enjoin righteousness and forbid evil, and say the truth about Muhammad صلى الله عليه وسلم], and perform As-Salat (Iqamat-as-Salat), and give Zakat. Then you slid back, except a few of you, while you are backsliders. (Tafsir Al-Qurtubi).
