Surah Ahqaf (سورۃ الاحقاف) with Urdu Translation

Al-Ahqaf (Arabic: اَلْأَحْقَافُ‎, "the sand dunes" or "the winding sand tracts") is the 46th chapter (surah) of the Qur'an with 35 verses (ayat). This is the seventh and last chapter starting with the letters ha-mim. Regarding the timing and contextual background of the supposed revelation (asbāb al-nuzūl), it is one of the late Meccan chapters (Makki Surah), except for verse 10 and possibly a few others which Muslims believe were revealed in Madinah a.k.a Madina.

The chapter covers various topics: It warns against those who reject the Quran (a.k.a Qur'an or Quraan), and reassures those who believe; it instructs Muslims to be virtuous towards their parents; it tells of the Prophet Hud and the punishment that befell his people, and it advises Muhammad to be patient in delivering his message of Islam.

A passage in chapter 15, which talks about a child's gestation and weaning, became the basis by which some Islamic jurists determined that the minimum threshold of fetal viability in Islamic law would be about 25 weeks. The name of the chapter comes from verse 21, where Hud is said to have warned his people "by the sand dunes" (bī al-Ahqaf).

The name al-Ahqaf, translated as "the sand dunes" or "the winding sand tracks", is taken from verse 21 of the chapter, which mentions "the brother of ʠĀd" (a nickname for the ancient Arabian prophet Hud), who "warned his people by the sand dunes". According to the 15th-16th century Quranic commentary Tafsir al-Jalalayn, "Valley of Ahqaf" was the name of the valley, located today in Yemen, where Hud and his people lived.

The chapter begins with a Muqattaʠat, the two-letter formula Hā-Mīm, the last of the seven chapters to do so. In the Islamic tradition, the meanings of such formulae at the beginnings of chapters are considered to be "known only to God". The following verses (2 - 9) warn against those who reject the Quran and reiterate the Quranic assertion that the verses of the Quran (a.k.a Qur'an or Quran) are revealed from God and were not composed by humans. The verses maintain that the AlQuran (a.k.a AlQur'an, Al-Quran, Al-Qur'an, Mushaf, Kuran and Koran) itself is a "clear proof" of God's signs, and challenge the disbelievers to produce another scripture, or "some vestige of knowledge", to justify their rejection.

Verse ten describes a "witness from the Children of Israel" who accepted the revelation. Most Quranic commentators believe that this verse - unlike most of the chapter - was revealed in Medina and the witness refers to Abdullah ibn Salam, a prominent Jew of Medina who converted to Islam, and whom Muhammad was reported to have described as one of the "People of Paradise".
