Abu Khaalid ‘Abdul-Kareem al-Miqrin narrates:
Whilst in the studio recording the programme “Questions by Telephone”, a brother by the name of Sa’d Khamees used to say to the Shaykh after every recording session:
“May Allaah reward you with good, O Shaykh, [and may] Allaah have mercy upon your parents.”
[And on this particular occasion] the Shaykh said: “Aameen! O Sa’d, and [as for] me?”
So Sa’d said: “[May] Allaah have mercy upon your parents.”
And [then] the Shaykh said: “Aameen, and [as for] me?”
It was then that Sa’d Khamees realised [what the Shaykh was saying] and [so] he said:
“[May] Allaah have mercy upon you and [may] Allaah have mercy upon your parents, and [may] He reward you with the best of rewards.”
[At this] the Shaykh smiled and [then] laughed, and we all laughed together.
