ḤADĪTH OF THE DAY

“ Mu'āth Ibn-Jabal said, "The Prophet, peace and blessings of God be upon him, delegated me over Yemen (to collect its (prescribed) alms(1)). Thus he ordered me to take from every thirty cows (2) a yearling bull or a yearling cow, and from every forty [cows] a heifer (3), and [to take] a Dinar (4) from each adult man(5), or a Ma'āfir (6) worth." Footnotes: (1)(Zakāt) One of the five pillars of Islām: A sum equivalent to 2.5% of the wealth stored over one year is paid by every Muslim annually for the benefit of the needy. (2) Here the word cow is used in its general meaning, i.e. any domestic bovine regardless of its sex. (3) The word heifer is used here to refer to a female cattle that is three years or older, regardless whether it had its first calf or not. (4) The Islamic Dinar is a specific weight of 22k gold (.917) equivalent to 4.25 grams. (Quoted from edinar) (5) Tax paid by non-Muslims living in a Muslim state, which is less than what Muslims pay annually in obligatory almsgiving. It is imposed on able-bodied non-Muslim men of military age. The tax is not levied on women, children, monks, the old, the sick, slaves, and the poor, and is subject to certain conditions. Non-Muslim citizens are free to practice their faith and to enjoy communal autonomy. They are entitled to protection from external aggression, and are exempt from military service, amongst other exemptions levied upon Muslim citizens. (6) Ma'āfir is a district in the city of Ta'z (in Yemen) known for its garments. Therefore he means: worth a Dinar of garments (as explained by Abu Dawwūd). ”

Sunan at-Tirmithiy كتاب الصوم باب ما جاء إذا أقبل الليل وأدبر النهار فقد أفطر الصائم

حَدَّثَنَا هَارُونُ بْنُ إِسْحَاقَ الْهَمْدَانِىُّ حَدَّثَنَا عَبْدَةُ بْنُ سُلَيْمَانَ عَنْ هِشَامِ بْنِ عُرْوَةَ عَنْ أَبِيهِ عَنْ عَاصِمِ بْنِ عُمَرَ عَنْ عُمَرَ بْنِ الْخَطَّابِ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا أَقْبَلَ اللَّيْلُ وَأَدْبَرَ النَّهَارُ وَغَابَتِ الشَّمْسُ فَقَدْ أَفْطَرْتَ. قَالَ وَفِى الْبَابِ عَنِ ابْنِ أَبِى أَوْفَى وَأَبِى سَعِيدٍ. قَالَ أَبُو عِيسَى حَدِيثُ عُمَرَ حَدِيثٌ حَسَنٌ صَحِيحٌ.
Umar Ibnul-Khattāb said, "The Messenger of God, peace and blessings of God be upon him, said, 'As the night looms and the day comes to an end, and as the sun sets (1), then your fasting is over.'" Footnote (1): i.e. when it disappears completely. This means that the approach of the night and the departure of the day must be caused by the setting of the sun, and not by any other temporary cause which blocks out sunlight.
