Sunan Abi Dawud 1702
The aforesaid tradition has also been transmitted by Shu’bah through a different chain of narrators to the same effect.  The version goes :
He said : Make it known for a year.  He said this three times.  He said: I do not know whether he said “for a year” or “for three years”.
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ شُعْبَةَ، بِمَعْنَاهُ قَالَ ‏
"‏ عَرِّفْهَا حَوْلاً ‏"‏ ‏.‏ وَقَالَ ثَلاَثَ مِرَارٍ قَالَ فَلاَ أَدْرِي قَالَ لَهُ ذَلِكَ فِي سَنَةٍ أَوْ فِي ثَلاَثِ سِنِينَ ‏.‏
