“For the Shahid in the Divine presence there will be six qualities: [1] he will be forgiven from the first moment his blood is spilled; [2] he shall see his seat in Paradise and be protected against the punishment of the grave; [3] he shall be safe from the Greatest Terror [the rising of the dead]; [4] he shall be crowned with the diadem of dignity, one ruby of which is worth more than the entire world and its contents; [5] he shall be coupled with seventy-two spouses from the wide-eyed maidens of Paradise; and [6] he shall be granted to intercede for seventy of his relatives.” Ahmad and al-Tirmidhi narrated it and the latter said: “This is a fair, sound, single-chained hadith” (hasan sahih gharib).

2. Anas said, Allah be well-pleased with him: The Messenger of Allah said, upon him blessings and peace:

“The servant in Paradise shall be married with seventy wives.” Someone said, “Messenger of Allah, can he bear it?” He said: “He will be given strength for a hundred.” Abu Nu`aym in Sifat al-Janna, al-`Uqayli in the Du`afa’, and al-Bazzar in his Musnad.

2a. From Zayd ibn Arqam, Allah be well-pleased with him, when an incredulous Jew or Christian asked the Prophet, upon him blessings and peace, “Are you claiming that a man will eat and drink in Paradise??” He replied: “Yes, by the One in Whose hand is my soul, and each of them will be given the strength of a hundred men in his eating, drinking, coitus, and pleasure.” Ahmad, al-Nasa’i in the Sunan al-Kubra, Ibn Abi Shayba, Ibn Hibban, and al-Hakim who declared it sahih.

Note that the Jews succeeded in “disappearing” all notion of a next life from their religion while the Christians succeeded in making it an ethereal abstraction. The Mu`tazila and other minority sects went that path also as do those who deny the reality of the punishment and reward of the grave, Hellfire, the Prophet’s Basin, the Bridge, the Balance, the Vision of Allah Most High etc.

3. Abu Sa`id al-Khudri said, Allah be well-pleased with him: The Messenger of Allah said, upon him blessings and peace:

“The humblest of the People of Paradise shall have eighty thousand servants and seventy-two wives. A palace of pearl and peridot(a: A pale green variety of chrysolite; used as a gemstone) and sapphire shall be erected for him as wide as the distance between al-Jabiya [a valley about 70 kms. East of Makka] and San`a’ [in Yemen].” Al-Tirmidhi and Ahmad narrated it.
