The above mentioned tradition has been reported by ‘Ikramah with a different chain of narrators. This version adds:

When he stood up, he said the takbir (Allah is most great) and said. . . .

حَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا أَبُو نُوحٍ، قُرَادٌ حَدَّثَنَا عِكْرِمَةُ، بِإِسْنَادِهِ بِلاَ إِخْبَارٍ وَمَعْنَاهُ قَالَ كَانَ إِذَا قَامَ بِاللَّيْلِ كَبَّرَ وَيَقُولُ ‏.‏
