It is narrated that once, on a Friday, people had gathered in the central mosque of Kufa. At that time, Sayyiduna ‘Ammar bin Yasir (may Allah be pleased with him) was the governor of Kufa on behalf of Sayyiduna ‘Umar (may Allah be pleased with him), and Sayyiduna ‘Abdullah bin Mas‘ud (may Allah be pleased with him) was the treasurer. Sayyiduna Ibn Mas‘ud (may Allah be pleased with him) saw the shadow and it had reached the length of a strap. He said,“If your companion (the governor) wants to act upon the Sunnah of the Prophet (peace and blessings be upon him), he will come out now.”By Allah! Sayyiduna Ibn Mas‘ud (may Allah be pleased with him) had not even finished his statement when Sayyiduna ‘Ammar bin Yasir (may Allah be pleased with him) came out saying,“Prayer, prayer!”
