The word(s) "glad" appears 67 time(s) in 64 verse(s) in Quran in Mohsin Khan translation.

(41) Is not He (better than your gods) Who guides you in the darkness of the land and the sea, and Who sends the winds as heralds of glad tidings, going before His Mercy (rain)? Is there any ilah (god) with Allah? High Exalted be Allah above all that they associate as partners (to Him)!

(42) And when Our Messengers came to Ibrahim (Abraham) with the glad tidings they said: "Verily, we are going to destroy the people of this [Lut (Lot's)] town (i.e. the town of Sodom in Palestine); truly, its people have been Zalimun [wrong-doers, polytheists disobedient to Allah, and who belied their Messenger Lut (Lot)]."

(43) And among His Signs is this, that He sends the winds as glad tidings, giving you a taste of His Mercy (i.e. rain), and that the ships may sail at His Command, and that you may seek of His Bounty, in order that you may be thankful.

(44) And if We send a wind [which would spoil the green growth (tilth) brought up by the previous rain], and they see (their tilth) turn yellow - behold, they then (after their being glad,) would become unthankful (to their Lord Allah as) disbelievers. [Tafsir At-Tabari]

(45) O Prophet (Muhammad صلى الله عليه وسلم)! Verily, We have sent you as witness, and a bearer of glad tidings, and a warner,

(46) And announce to the believers (in the Oneness of Allah and in His Messenger Muhammad صلى الله عليه وسلم) the glad tidings, that they will have from Allah a Great Bounty.

(47) And We have not sent you (O Muhammad صلى الله عليه وسلم) except as a giver of glad tidings and a warner to all mankind, but most of men know not.

(48) Verily We have sent you with the truth, a bearer of glad tidings and a warner. And there never was a nation but a warner had passed among them.

(49) You can only warn him who follows the Reminder (the Qur'an), and fears the Most Gracious (Allah) unseen. Bear you to such one the glad tidings of forgiveness, and a generous reward (i.e. Paradise).

(50) So We gave him the glad tidings of a forbearing boy.
