question #3 Sahih al-Bukhari 1184, Book 19, Hadith 61 : What factors might prevent someone from performing additional voluntary prayers?

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 (ﷺ).” I asked
him, “What prevents you from offering it now?” He replied, “Business.”
