The First One Who Made Garment He (Idris) was the first one who sewed a garment and wore it. وَهوَ أَوَّلُ مَن خاطَ الثّيابَ وَلَبسَها. His Meditation Upon God’s Grandeur Idris meditated upon the grandeur of Allah, Great be His Glory, saying: For these heavens and the earths, for this great creation, the sun, the Moon the stars, the clouds, rain and all these objects, there is a Lord who is their Manager, why should I not worship this Lord as He deserves.
Then, he made contact with his tribe, preaching them, giving them advice, warning them, and inviting them to worship the Creator of all these objects.
Idris And Love Of Worship (When Idris invited people) they responded to him one by one until they became seven, then seventy, then seven hundred until they became one thousand. Idris said: Let us select a hundred men from among a thousand. They did so. Then they selected seventy men from among a hundred and then ten and eventually seven. Then, he said to them: Now you — seven persons — pray and the rest of us will say Amen so that God, Great be His Glory will guide us to worshipping Him.
They laid their hands on the earth and prayed for a long time but they gained nothing. Then, they raised their hands towards the heaven. It was then that God — Glorified and Honored —, inspired Idris guiding him those with him to worshipping Him. Since then, they worshipped God — Glorified and Honored — and did not associate anything with Him till God raised Idris to heavens.
