Shaykh Muhammad ibn Abdil-Wahhaab al-Aqeel said:
"Be lenient with them, for this is the era of strangeness, today is the time of strangeness. If you see a person with a whiff of Salafiyyah in him, then kiss his forehead – a whiff like this [and the Shaykh draws breath through his nose as if to smell], a whiff OK? – then kiss his forehead and tell him that you love him."
