Muwatta Imam Malik Book of Hajj, Hadith 244
Yahya related to me from Malik from Zayd ibn Aslam that a man came to Umar ibn al-Khattab and said, "Amir al-muminin, I killed some locusts with my whip when I was in ihram," and Umar said to him, "Give a handful of food."
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، أَنَّ رَجُلاً، جَاءَ إِلَى عُمَرَ بْنِ الْخَطَّابِ فَقَالَ يَا أَمِيرَ الْمُؤْمِنِينَ إِنِّي أَصَبْتُ جَرَادَاتٍ بِسَوْطِي وَأَنَا مُحْرِمٌ . فَقَالَ لَهُ عُمَرُ أَطْعِمْ قَبْضَةً مِنْ طَعَامٍ .
