“I once asked abu ‘Abd Allah (a.s.), about reading from al-Quran or speaking of Allah, most Blessed, most High, and that which one is more virtuous when I perform Tawaf. He (the Imam) said, ‘Reading is more virtuous.’ I then asked, ‘What happens if one comes across a passage for which Sajdah (prostration) is obligatory.’ He (the Imam) said, ‘He must make a gesture with his head toward al-Ka‘bah.’”
