Yahya related to me from Malik from Zayd ibn Aslam from Ata ibn Yasar that the Messenger of Allah ﷺ sent a gift to Umar ibn al-Khattab, and Umar returned it. The Messenger of Allah ﷺ said, "Why did you return it?" He said, "Messenger of Allah, didn't you tell us that it is better for us not to take anything from anyone?" The Messenger of Allah ﷺ said, "That is by asking. Provision which Allah gives you is different from asking." Umar ibn al-Khattab said, "By the One in whose hand my self is, I will not ask anything from anyone, and anything that comes to me without my asking for it, I will accept."  

أَنَّ رَسُولَ اللَّهِ ﷺ أَرْسَلَ إِلَى عُمَرَ بْنِ الْخَطَّابِ بِعَطَاءٍ فَرَدَّهُ عُمَرُ فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ لِمَ رَدَدْتَهُ فَقَالَ يَا رَسُولَ اللَّهِ أَلَيْسَ أَخْبَرْتَنَا أَنَّ خَيْرًا لأَحَدِنَا أَنْ لاَ يَأْخُذَ مِنْ أَحَدٍ شَيْئًا فَقَالَ رَسُولُ اللَّهِ ﷺ إِنَّمَا ذَلِكَ عَنِ الْمَسْأَلَةِ فَأَمَّا مَا كَانَ مِنْ غَيْرِ مَسْأَلَةٍ فَإِنَّمَا هُوَ رِزْقٌ يَرْزُقُكَهُ اللَّهُ فَقَالَ عُمَرُ بْنُ الْخَطَّابِ أَمَا وَالَّذِي نَفْسِي بِيَدِهِ لاَ أَسْأَلُ أَحَدًا شَيْئًا وَلاَ يَأْتِينِي شَىْءٌ مِنْ غَيْرِ مَسْأَلَةٍ إِلاَّ أَخَذْتُهُ
