"Speaking Persian Causes Hypocrisy" [?]

[Moosaa.Richardson]

Al-Haakim reported in his Mustadrak (4/87) that Ibn ‘Umar allegedly narrated from the Messenger of Allaah (may Allaah raise his rank and grant him peace):

من أحسن منكم أن يتكلم بالعربية فلا يتكلمن بالفارسية، فإنه يورث النفاق

“Those of you who speak Arabic proficiently must not speak in Persian, since it causes hypocrisy.”

This hadeeth has been idenitified as mowdhoo’ (fabricated), since the early criticism of ath-Thahabee for al-Haakim’s book when he identified ‘Umar ibn Haaroon the liar in the chain, to the later scholars of hadeeth like Al-Albaanee in Silsilat al-Ahaadeeth ad-Dha’eefah (#523).
