Marthad b. ‘Abdallah said:

I went to ‘Uqba al-Juhani and said, “I can tell you something about Abu Tamim which will make you wonder. He prays two <i>rak'as</i> before the sunset prayer.” ‘Uqba replied, “We used to do so in the time of God’s Messenger.” I asked, “What prevents you now?” and he replied, “Work.” Bukhari transmitted it.

وَعَن مرْثَد بْنِ عَبْدِ اللَّهِ قَالَ: أَتَيْتُ عُقْبَةَ الْجُهَنِيَّ فَقُلْتُ: أَلَا أُعَجِّبُكَ مِنْ أَبِي تَمِيمٍ يَرْكَعُ رَكْعَتَيْنِ قَبْلَ صَلَاةِ الْمَغْرِبِ؟ فَقَالَ عُقْبَةُ: إِنَّا كُنَّا نَفْعَلُهُ عَلَى عَهْدِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ. قُلْتُ: فَمَا يَمْنَعُكَ الْآنَ؟ قَالَ: الشّغل. رَوَاهُ البُخَارِيّ
