Assalaamu `alaykum waRahmatullahi Wabarakatuh
Imam Abu Ya’la has mentioned the same Hadith in his Musnad with the inclusion of Fardh Salaah. Therefore, the said Zikr and Dua should be made after Fardh Salaah.
مسند أبي يعلى- مشكول - (ج 4 / ص 198)

حَدَّثَنَا وَاصِلُ بْنُ عَبْدِ الأَعْلَى الْكُوفِيُّ ، حَدَّثَنَا ابْنُ فُضَيْلٍ ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ إِسْحَاقَ ، عَنِ الْحُسَيْنِ بْنِ أَبِي سُفْيَانَ ، عَنْ أَنَسِ بْنِ مَالِكٍ ، قَالَ : زَارَ رَسُولُ اللَّهِ صلى الله عليه وسلم أُمَّ سُلَيْمٍ فَصَلَّى فِي بَيْتِهَا صَلاةَ تَطَوُّعٍ ، فَقَالَ : يَا أُمَّ سُلَيْمٍ ، إِذَا صَلَّيْتِ الْمَكْتُوبَةَ ، فَقُولِي : سُبْحَانَ اللَّهِ عَشْرًا ، وَاللَّهُ أَكْبَرُ عَشْرًا ، ثُمَّ سَلِي مَا شِئْتِ ، فَإِنَّهُ يَقُولُ لَكِ : نَعَمْ ، ثَلاثَ مَرَّاتٍ
And Allah knows best
