Mishkat al-Masabih 17 Prescribed Punishments كتاب الحدود 2

وَعَنْ زَيْدِ بْنِ خَالِدٍ قَالَ: سَمِعْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَأْمُرُ فِيمَنْ زَنَى وَلَمْ يُحْصَنْ جَلْدَ مِائَةٍ وَتَغْرِيبَ عَامٍ. رَوَاهُ البُخَارِيّ

Zaid b. Khalid told that he heard God’s Messenger giving command that an unmarried man who committed fornication should receive a hundred lashes and be banished for a year. Bukhari transmitted it.
