أَحْصَيْنَاهُ : We have recorded it. Allah (swt) says:

 ﴾إِذْ يَتَلَقَّى الْمُتَلَقِّيَانِ عَنِ الْيَمِينِ وَعَنِ الشِّمَالِ قَعِيدٌ % مَّا يَلْفِظُ مِن قَوْلٍ إِلَّا لَدَيْهِ رَقِيبٌ﴿

 (When the two receivers receive, seated on the right and on the left. % Man does not utter any word except that with him is an observer prepared [to record].) (Qaf: 17-18)
