ahl i qibla.

[adnan42]

assalamualaikum..
can anyone please clarify who are ahl i qibla??
i was under the impression ahl i qibla are the one who pray toward the kaba. but someone told me ahl i qibla doesnot mean those who pray towards kaba but the one who believes in all articles of faith.
so if one reject zakat as a one of fundamental of islam he is not ahl i qibla even if he prays towards kaba. or like a ahmadiyah even tho they pray towards kaba they are not ahl i qibla...
