Muwatta Malik, Book 20, Hadith 217 (USC-MSA) ⓘ
Yahya related to me from Malik that Nafi said, "They say that Umar ibn al-Khattab used to send men out to bring people in from beyond al-Aqaba."
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّهُ قَالَ زَعَمُوا أَنَّ عُمَرَ بْنَ الْخَطَّابِ، كَانَ يَبْعَثُ رِجَالاً يُدْخِلُونَ النَّاسَ مِنْ وَرَاءِ الْعَقَبَةِ .
