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 الزهد باب فى التوكل على الله

حَدَّثَنَا عَلِىُّ بْنُ سَعِيدٍ الْكِنْدِىُّ حَدَّثَنَا ابْنُ الْمُبَارَكِ عَنْ حَيْوَةَ بْنِ شُرَيْحٍ عَنْ بَكْرِ بْنِ عَمْرٍو عَنْ عَبْدِ اللَّهِ بْنِ هُبَيْرَةَ عَنْ أَبِى تَمِيمٍ الْجَيْشَانِىِّ عَنْ عُمَرَ بْنِ الْخَطَّابِ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم لَوْ أَنَّكُمْ كُنْتُمْ تَوَكَّلُونَ عَلَى اللَّهِ حَقَّ تَوَكُّلِهِ لَرُزِقْتُمْ كَمَا تُرْزَقُ الطَّيْرُ تَغْدُو خِمَاصًا وَتَرُوحُ بِطَانًا. قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ لاَ نَعْرِفُهُ إِلاَّ مِنْ هَذَا الْوَجْهِ. وَأَبُو تَمِيمٍ الْجَيْشَانِىُّ اسْمُهُ عَبْدُ اللَّهِ بْنُ مَالِكٍ.
The Messenger of God, peace and blessings of God be upon him, said, "If only you were to trust and rely on God as He ought to be trusted and relied on, you would have been provided with sustenance just as the birds are: they set out hungry in the early morning and return full-bellied in the afternoon."
This ḥadīth does not imply that we should remain idle while waiting for God's sustenance rather seeking it while trusting that God is the Sustainer.
