(Imām Bukhārī narrates): Mūsā ibn Ismā'īl narrated to us, he said: Abū 'Awānah narrated to us, from 'Amr, from Tāwūs, from Ibn 'Abbās, may Allāh be pleased with them both, from the Prophet ﷺ, he said:
I have been commanded that I should perform sajdah upon seven limbs, and neither fold up the hair nor the garment.
