صحيح البخاري

Narrated Marthad bin `Abdullah Al-Yazani:

I went to `Uqba bin 'Amir Al-Juhani and said, "Is it not surprising that Abi Tamim offers two rak`at before the Maghrib prayer?" `Uqba said, "We used to do so in the lifetime of Allah's Messenger." I asked him, "What prevents you from offering it now?" He replied, "Business."
