۞ ضَرَبَ ٱللَّهُ مَثَلًا عَبْدًۭا مَّمْلُوكًۭا لَّا يَقْدِرُ عَلَىٰ شَىْءٍۢ وَمَن رَّزَقْنَٰهُ مِنَّا رِزْقًا حَسَنًۭا فَهُوَ يُنفِقُ مِنْهُ سِرًّۭا وَجَهْرًا ۖ هَلْ يَسْتَوُۥنَ ۚ ٱلْحَمْدُ لِلَّهِ ۚ بَلْ أَكْثَرُهُمْ لَا يَعْلَمُونَ
Allah coineth a similitude: (on the one hand) a (mere) chattel slave, who hath control of nothing, and (on the other hand) one on whom we have bestowed a fair provision from Us, and he spendeth thereof secretly and openly. Are they equal? Praise be to Allah! But most of them know not.

Sahih al-Bukhari
Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)
Chapter: The Ghazwa of Al-Khandaq or Al-Ahzab Battle
Narrated Anas:
Al-Muhajirun (i.e. the Emigrants) and the Ansar were digging the trench around Medina and were carrying the earth on their backs while saying, "We are those who have given the pledge of allegiance to Muhammad for Islam as long as we live." The Prophet (ﷺ) said in reply to their saying, "O Allah! There is no goodness except the goodness of the Hereafter; so please grant Your Blessing to the Ansar and the Emigrants." The people used to bring a handful of barley, and a meal used to be prepared thereof by cooking it with a cooking material (i.e. oil, fat and butter having a change in color and smell) and it used to be presented to the people (i.e. workers) who were hungry, and it used to stick to their throats and had a nasty smell.
