Mishkat al-Masabih 6 Zakat كتاب الزكاة 161

وَعَن عَائِشَة قَالَت: يَا رَسُول الله إِن لِي جَارَيْنِ فَإِلَى أَيِّهِمَا أُهْدِي؟ قَالَ: «إِلَى أقربهما مِنْك بَابا» . رَوَاهُ البُخَارِيّ

‘A’isha said that when she told God’s messenger she had two neighbours and asked to which of them she should send a present, he replied, “To the one who lives nearer you.” Bukhari transmitted it.
