…and as for His words, “Say, ‘Be stones or iron (50) or any other created thing that you deem even harder’” (al-Isra 50–51), this relates to a different point of exegesis. In brief, iron, so long as it is left un-worked, is at present more resistant than stone; yet once it is smelted it becomes pliable, whereas stone does not. Allah knows best.
Abu Nuʿaym said:
If it be asked, “Allah softened iron for David (upon him be peace) until he fashioned from it ample coats of mail,” the reply is that stones and massive rocks were softened for Muhammad ﷺ. They even became a cave that concealed him from the idol-worshippers. On the day of Uhud he inclined his head toward the mountain to hide himself from them, and Allah softened the mountain so that he was able to insert his head into it. This is more wondrous, for fire softens iron, yet no one has ever seen fire soften stone. He added: This outward trace still remains for people to see.
He went on: Likewise, in one of the ravines of Mecca there is a stone from a solid mountain to which the Prophet ﷺ leaned in prayer; the stone softened until the imprint of his forearms and elbows remained in it. This is well known—pilgrims purposely visit it. The very rock in Jerusalem became like dough on the night of the Night Journey, and he tied his mount, al-Buraq, to it; people touch that spot up to this day (1).
What he mentioned about the day of Uhud and about certain ravines of Mecca is extremely unusual. Perhaps he himself produced a chain of transmission for it earlier, but it is not found in the famous works of the Sirah.
As for the tying of the mount to the rock, that is sound; it was Gabriel who tied it, as is recorded in Sahih Muslim (2), may Allah have mercy on him.
Concerning His words, “We granted him wisdom and decisive speech” (Sad 20): the wisdom granted to Muhammad ﷺ and the law revealed for him are more complete than every wisdom and law ever granted to the prophets before him—may Allah’s blessings be upon him and upon them all—for Allah combined in him the virtues of those who preceded him, added to them, and perfected for him what He had given no one before. The Prophet ﷺ said, “I have been given the concise, all-embracing words, and wisdom has been compressed for me in a concise form” (3). There is no doubt that the Arabs are the most eloquent of peoples, and the Prophet ﷺ was the most eloquent of them in speech and the most comprehensive in every noble trait.
A discussion of what was bestowed upon Solomon son of David (upon him be peace)
Allah the Exalted said: “So We subjected to him the wind, which blew gently at his command wherever he wished (36); and We subjected the devils—every builder and diver (37); and others bound together in chains (38). ‘This is Our gift, so give freely or withhold without reckoning’ (39); and truly for him with Us is nearness and a goodly return (40)” (Sad 36–40).
He also said: “And for Solomon We subjected the stormy wind, which blew at his command toward the land We had blessed—We are aware of all things (81); and of the devils were those who dived…”
