Question: "What's the ruling on a Muslim that doesn't pray?" Answer: "The ruling is YOU invite him to the masjid!" ~Shk. Muhammad alGhazali (d. 1996)
Sheikh Mohammed al-Ghazali al-Saqqa appears to be the sheikh in question, but I'm unsure about the reliability of this quote.
Question: When asked "what's the ruling on a Muslim that doesn't pray" did Sheikh Mohammed al-Ghazali reply to the effect of "the ruling is YOU invite him to the masjid"?
I found other sources for this online, but nothing reliable. TopIslamic.com writes:
Shaikh Muhammad Al-Ghazali was asked, “What is the ruling of the one who left prayer?” He replied, “The ruling is for you to take them along with you to the mosque.” Be a caller, not a judge.
