Is there a difference between *akhrajahu* and *kharrajahu*? Since Ibn Rajab uses *kharrajahu* in his books, is it a term specific to him?

The questioner : A question regarding terminology: Ibn Rajab’s convention in most of his books is that when he mentions a hadith, he says *akhrajahu al-Bukhari* (al-Bukhari narrated it), whereas he says *kharrajahu al-Bukhari* (al-Bukhari traced it to its source). Is there a difference between *akhrajahu* and *kharrajahu*, or is it merely a convention?

The Shaykh : No, the present tense verb... the past tense intransitive verb is sometimes formed with an alif and sometimes by doubling the root letter, so *akhraj* and *kharraj* mean the same thing.

The questioner : Ibn Rajab’s convention is consistent across all his books.
