The Book of As-Siyâm (the Fasting)

Abu Hurairah Narrated from:

Allâh's Messenger صلى الله عليه وسلم said, "When the month of Ramadân starts, the gates of the heaven are opened and the gates of Hell are closed and the devils are chained." ( Sahîh Al-Bukhâri, Hadîth No. 123, Vol. 3)

`Abdullah bin `Umar Narrated from:

Allâh's Messenger صلى الله عليه وسلم mentioned Ramadân and said, "Do not observe Saum (fast) unless you see the crescent (of Ramadân), and do not give up Saum till you see the crescent (of Shawwâl), and if the sky is overcast (if you cannot see the crescent), then act on estimation (i.e. count Sha'bân as thirty days)." ( Sahîh Al-Bukhâri, Hadîth No. 130, Vol. 3)

Ibn 'Umar Narrated from:

The Prophet صلى الله عليه وسلم (holding out his ten fingers thrice), said, "The month is thus and thus and thus," namely thirty days. Then (holding out his ten fingers twice and then nine fingers), he said, "It may be thus and thus and thus," namely twenty-nine days. He meant once thirty days and once twenty-nine days. ( Sahîh Al-Bukhârî, Hadîth No. 222, Vol. 7 )

Ibn 'Umar Narrated from:

The Prophet صلى الله عليه وسلم said, "We are an illiterate nation; we neither write, nor know accounts. The month is like this and this, i.e. sometimes of 29 days and sometimes of 30 days." ( Sahîh Al-Bukhârî, Hadîth No. 137, Vol. 3 )

Abu Hurairah Narrated from:

The Prophet صلى الله عليه وسلم, or said, Abûl-Qâsim said, "Start Saum (fast) on seeing the crescent (of Ramadân), and give up Saum on seeing the crescent (of Shawwâl), and if the sky is overcast (and you cannot see the crescent), complete thirty days of Sh'abân." ( Sahîh Al-Bukhârî, Hadîth No. 133, Vol. 3 )

Abu Hurairah Narrated from:

The Prophet صلى الله عليه وسلم said, "None of you should observe Saum (fast) for a day or two ahead of Ramadân, unless he has the habit of observing Saum ( Nawâfil ), (and if his Saum coincides with that day) then he can observe Saum that day." ( Sahîh Al-Bukhârî, Hadîth No. 138, Vol. 3 )

Umm Salamah Narrated from:

The Prophet صلى الله عليه وسلم took an oath that he would not enter upon some of his wives for one month. But when twenty-nine days had elapsed, he went to them in the morning or evening. It was said to him, "O Allâh's Prophet ﷺ! You had taken an oath that you would not enter upon them for one month." He replied, "The month can be of twenty-nine days." ( Sahîh Al-Bukhârî, Hadîth No. 130, Vol. 7 )

Narrated Abû Bakra رضى الله عنه : The Prophet ﷺ said, "The two months of 'Eid i.e. Ramadân and Dhul-Hijja, do not decrease (in superiority)." [1] ( Sahîh Al-Bukhârî, Hadîth No. 136, Vol. 3 )

`Adi bin Hatim Narrated from:

When the Verses were revealed: 'Until the white thread appears to you, distinct from the black thread,' I took two (hair) strings, one black and the other white, and kept them under my pillow and went on looking at them throughout the night but could not make anything out of it. So, the next morning I went to Allâh's Messenger ﷺ and told him the whole story. He explained to me, "That Verse means the darkness of night and the whiteness of dawn." (Sahîh Al-Bukhâri, Hadîth No. 140, Vol. 3)

Sahl bin Sa`d Narrated from:

When the following Verses were revealed: 'Eat and drink until the white thread appears to you, distinct from the black thread,' and 'of dawn' was not revealed, some people who intended to observe Saum (fast), tied black and white threads to their legs and went on eating till they differentiated between the two. Allâh تعالى then revealed the words, 'of dawn', and it became clear that meant night and day. (Sahîh Al-Bukhâri, Hadîth No. 141, Vol. 3)
