The word(s) "mother" appears 47 time(s) in 35 verse(s) in Quran in Muhammad Pickthal translation.

(21) And We had before forbidden foster-mothers for him, so she said: Shall I show you a household who will rear him for you and take care of him?

(22) So We restored him to his mother that she might be comforted and not grieve, and that she might know that the promise of Allah is true. But most of them know not.

(23) And never did thy Lord destroy the townships, till He had raised up in their mother(-town) a messenger reciting unto them Our revelations. And never did We destroy the townships unless the folk thereof were evil-doers.

(24) And We have enjoined upon man concerning his partners - His mother beareth him in weakness upon weakness, and his weaning is in two years - Give thanks unto Me and unto thy parents. Unto Me is the journeying.

(25) Allah hath not assigned unto any man two hearts within his body, nor hath He made your wives whom ye declare (to be your mothers) your mothers, nor hath He made those whom ye claim (to be your sons) your sons. This is but a saying of your mouths. But Allah saith the truth and He showeth the way.

(26) The Prophet is closer to the believers than their selves, and his wives are (as) their mothers. And the owners of kinship are closer one to another in the ordinance of Allah than (other) believers and the fugitives (who fled from Mecca), except that ye should do kindness to your friends. This is written in the Book (of nature).

(27) O Prophet! Lo! We have made lawful unto thee thy wives unto whom thou hast paid their dowries, and those whom thy right hand possesseth of those whom Allah hath given thee as spoils of war, and the daughters of thine uncle on the father's side and the daughters of thine aunts on the father's side, and the daughters of thine uncle on the mother's side and the daughters of thine aunts on the mother's side who emigrated with thee, and a believing woman if she give herself unto the Prophet and the Prophet desire to ask her in marriage - a privilege for thee only, not for the (rest of) believers - We are Aware of that which We enjoined upon them concerning their wives and those whom their right hands possess - that thou mayst be free from blame, for Allah is ever Forgiving, Merciful.

(28) He created you from one being, then from that (being) He made its mate; and He hath provided for you of cattle eight kinds. He created you in the wombs of your mothers, creation after creation, in a threefold gloom. Such is Allah, your Lord. His is the Sovereignty. There is no Allah save Him. How then are ye turned away?

(29) And thus We have inspired in thee a Lecture in Arabic, that thou mayst warn the mother-town and those around it, and mayst warn of a day of assembling whereof there is no doubt. A host will be in the Garden, and a host of them in the Flame.

(30) And We have commended unto man kindness toward parents. His mother beareth him with reluctance, and bringeth him forth with reluctance, and the bearing of him and the weaning of him is thirty months, till, when he attaineth full strength and reacheth forty years, he saith: My Lord! Arouse me that I may give thanks for the favour wherewith Thou hast favoured me and my parents, and that I may do right acceptable unto Thee. And be gracious unto me in the matter of my seed. Lo! I have turned unto Thee repentant, and lo! I am of those who surrender (unto Thee).
