Sa’īd b. Al-Musayyib reports from his father, “I was once sitting with ʿUmar when a group of people arrived from Al-Shām. ʿUmar enquired about them and how they were; he asked, ‘Do the people of Al-Shām hasten to break the fast.’ He said, ‘Yes.’ [ʿUmar] said, ‘They will not cease to remain upon good as long as they do this, and do not wait for the stars [to come out] as the people of Irāq do.’”

ʿAbd Al-Razzāq Al-Ṣan’ānī, Al-Muṣannaf 4:225.

‘Amr b. Maymūn Al-Awdī reports, “The Companions of Muḥammad – Allāh’s peace and blessings be upon him – used to be the quickest to break the fast and the slowest in taking the pre-dawn meal.”

Ibid. p226.

Ibn Al-Musayyib also reports that ʿUmar wrote to the commanders of the various regions, ‘Do not be of the procrastinators when breaking the fast, and nor of those who wait for the stars before they start praying [al-maghrib].’

Ibid. p225.

Mūsā b. Anas reports that Anas [ibn Mālik] used to have his slave-girl go to the top of his house, instructing her, ‘When the horizon becomes even (evenly lit, marking sunset), tell me.’

Ibn Abī Shaybah, Al-Muṣannaf 2:430.

Abū Al-Tiyāḥ Al-Ḍaba’ī reports that “he used to break fast with Ibn ‘Abbās during Ramaḍān. When evening approached he would send a girl from his household to the roof [to look out], and when the sun set he would make the call to prayer (adhān). He would eat with us, and when he had finished, the call for the commencement of prayer {iqāmah) would be given, and he would pray, and we would pray with him.”

Ibid. p429.
