Source (Arabic)
إذا أراد المشرکون أن یقتلوه بالظّلم أرسلوا إلیه أُمّه لتنصحه لعلّ یتوب ویتّبع الّذین کفروا بالله ربّ العالمین
Translation
When the infidels, so unjustly, decided to put him to death, they sent and fetched his mother, that perchance she might admonish him, and induce him to recant his faith, and follow in the footsteps of them that have repudiated the truth of God, the Lord of all worlds.
