Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Safwan ibn Yahya from Ya’qub ibn Shu’ayb who has said the following: “I once asked abu ‘ Abd Allah (a.s.), about feeling the corner (of al-Ka‘bah). He (the Imam) replied, ‘Istilam (feeling) is touching it (the Black Stone) with your belly and al-Mash (touching) is wiping it with your hand.’” صحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (18/17))
