The Quraysh and the Banu Bakkah

The Quraysh are not united there's always bickering Allah says in the Quran ta sibu hum jamiyan wa kurubu hum shatah you think they're one group but in reality their hearts are disunited. This disunity began from the very exiting of makkah that one group began debating amongst themselves and then they brought up an old rivalry that existed before the coming of islam this is paranoia it's been now 10 years since this rivalry was last seen.
