Ibraaheem ibn ‘Abdil-’Azeez ash-Shithree narrates:
I was in the company of the Shaykh once, when someone telephoned the Shaykh seeking a fatwa. Just at that time, the mu.adhdhin began calling the adhaan, so the Shaykh said to the questioner:
“We shall now [listen and] respond to the adhaan,” and he placed the telephone handset down beside him.
When he finished responding to the [call of the] mu.adhdhin and reciting the well-known supplication after the adhaan, he turned to speak to the questioner [still waiting] on the phone, and answered his question.
This is indicative of the Shaykh’s consciousness of implementing the Sunnah in all [his] affairs.
