Al Husayn Bin Muhammad Al Ashary, from Abdullah Bin Aamir, from Ali Bin Mahziyar, from Fazalat Bin Ayoub, from Al Husayn Bin Usman, from Ibn Muskan, from Al Haris Bin Al Mugheira, and Umar Bin Hanzala, and Mansour Bin Hazim who said, ‘We used to estimate the sun at Al-Medina with the (shadow being of a) cubit. So Abu Abdullah -asws said: ‘I -asws shall notify you with (something) more clear than this.
When the sun (starts to) decline, so the time for Al-Al-Zohr has entered, unless in front of it is an Optional ( Salāt ); and that is up to you, if you so desire to, you prolong, and if you so desire to, you shorten’.
And Sa’ad reported from Musa Bin Al Hassan, from Al Hassan Bin Al Husayn Al Lului, from Safwan Bin Yahya, from Al Haris Bin Al Mugheira Al Nazary and Umar Bin Hanzala, from Mansour – Similar to it, and in it is: ‘It is up to you. And if you would like to lighten your Optional ( Salāt ), so (it is) when you are free from your Optional ( Salāt ), and if you prolong it, so it is when you are free from your Optional ( Salāt )’ (i.e.,) the time for Al-Zohr’.
