When I came from Ethiopia (to Medina), I was a young girl. Messenger of Allah ﷺ made me wear a sheet having marks on it. Messenger of Allah ﷺ was rubbing those marks with his hands saying, "Sanah! Sanah!" (i.e. good, good).
قَدِمْتُ مِنْ أَرْضِ الْحَبَشَةِ وَأَنَا جُوَيْرِيَةٌ فَكَسَانِي رَسُولُ اللَّهِ ﷺ خَمِيصَةً لَهَا أَعْلاَمٌ فَجَعَلَ رَسُولُ اللَّهِ ﷺ يَمْسَحُ الأَعْلاَمَ بِيَدِهِ وَيَقُولُ سَنَاهْ سَنَاهْ قَالَ الْحُمَيْدِيُّ يَعْنِي حَسَنٌ حَسَنٌ
