AI nawāh is the stone of dates, grape seed, and other fruit such as olives and apricots. Nawā are the seeds or stones of kinds of berry fruit, irrespective of whether it has one stone or more. The date seed has a small embryo, with a small cotyledon; the endosperm fills the major bulk of the seed. The stone of the olive, apricot, peach, and almond is actually a seed, surrounded by the woody endocarp (the inner part of the fruit wall). Thus nawāh may denote a seed, or a seed and its endocarp.
Allah, the Merciful, the Compassionate, says: “It is Allah Who causeth the seed-grain and the date-stone to split and sprout. He causeth the living to issue from the dead, and he is the one to cause the dead to issue from the living. “that is Allah: then how are ye deluded away from the truth?” Surat Al-Anaam, verse 95
Asma' daughter of Abu Bakr reported that she was married to Zubair. He had neither land nor wealth nor slave nor anything else like it except a bom. She further said: I grazed his horse. provided fodder to it and looked after it, and ground dates-stones for his camel. Besides this, I grazed the camel, made arrangements for providing it with water and patched up the leather bucket and kneaded the flour. But I was not proficient in baking the bread, so my female neighbours used to bake bread for me and they were sincere women. She further said: I was carrying on my head the stones of the dates from the land of Zubair which Allah's Messenger (ﷺ) had endowed him and it was at a distance of two miles (from Medina). She add: As I was one day carrying the atones of dates upon my head I happened to meet Allah's Messenger (ﷺ) along with a group of his Companions. He called me and said (to the camel) to sit down so that he should make cite ride behind hirn. (I told my husband: ) I felt shy and remembered your jealousy, whereupon he said: By Allah. the carrying of the stone dates upon your bead is more severe a burden than riding with him. She said: (I led the life of hardship) until Abu Bakr sent afterwards a female servant who took upon herself the responsibility of looking after the horse and I felt as it she had emancipated me.
