Hifz means memorization of the Quran. Hufaz names the Muslim belief that whoever memorizes the Quran and acts upon it will be rewarded and honoured by
God.
Abdullah ibn Amr narrated that
Muhammad said: "It shall be meaning to the one who memorized the 'Recite, and rise up, recite (melodiously) as you would recite in the world. Indeed your rank shall be at the last
Āyah you recited" (Jami` at-Tirmidhi 2914) Having memorized the Quran, the
hafiz or
hafiza must not forget it. Ensuring perfect recall of the verses requires constant practice. Yearly, thousands of students master and memorize the Quran. In Pakistan,
Muhammad Hanif Jalandhari, the general secretary of the
Wafaq-ul-Madaris, a central board accounting for most
religious seminaries in Pakistan that adhere to the
Deobandi sect, says that, in its network of madrasas, "one million children have become Hafiz-e-Quran after an exam was introduced in 1982", with more than 78,000 (including 14,000 girls) every year, which he compared to the yearly output of
Saudi Arabia, at 5,000. == Cultural differences ==
