This hadith is listed as number 1730 in Maktaba Shamila
حَدَّثَنِي هَنَّادُ بْنُ السَّرِيِّ ، حَدَّثَنَا أَبُو الأَحْوَصِ ، عَنْ أَشْعَثَ ، عَنْ أَبِيهِ ، عَنْ مَسْرُوقٍ ، قَالَ : سَأَلْتُ عَائِشَةَ ، عَنْ عَمَلِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، فَقَالَتْ : كَانَ يُحِبُّ الدَّائِمَ ، قَالَ : قُلْتُ : أَيَّ حِينٍ كَانَ يُصَلِّي ؟ فَقَالَتْ : " كَانَ إِذَا سَمِعَ الصَّارِخَ ، قَامَ فَصَلَّى " .
Masruq is reported to have asked 'A'isha about the action (most pleasing to) the Messenger of Allah (ﷺ) . She said: He (the Holy Prophet) loved (that action) which one keeps on doing regularly. I said (to 'A'isha): When did he pray (at night)? She replied: When he heard the cock crow, he got up and observed prayer.
