Hadith 1752B1

قَالَ يَحْيَى : وَسُئِلَ مَالِك عَمَّنْ سَلَّمَ عَلَى الْيَهُودِيِّ أَوِ النَّصْرَانِيِّ هَلْ يَسْتَقِيلُهُ ذَلِكَ ؟ فَقَالَ : لَا
Imam Malik, may Allah have mercy on him, was asked: If someone greets a Jew or a Christian, that is, says "As-salamu Alaikum" to him, should he then revoke it? He said: No, rather he should repent and seek forgiveness, because he acted against the command.
