It is narrated from Sayyiduna Sa'id bin Jubayr (may Allah be pleased with him) that he said: I asked Sayyiduna Ibn Abbas (may Allah be pleased with them both) whether, in the verse "And they have made the angels, who are the servants of the Most Merciful" [al-Zukhruf: 19] , it is 'ibad al-Rahman' (the servants of the Most Merciful) or ''inda al-Rahman' (with the Most Merciful). He replied: 'ibad al-Rahman'. I said: But in my copy of the Qur'an it is written ''inda al-Rahman'! He said: Erase it and write 'ibad al-Rahman'. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), and they did not record it.
