Sunan Abu Dawood : 2330
Sulaiman bin Abdur-Rahman al-Dimashqi said about this tradition that al-Walid said: I heard Abu Amr al-Auzai say:
حَدَّثَنَا سُلَيْمَانُ بْنُ عَبْدِ الرَّحْمَنِ الدِّمَشْقِيُّ فِي هَذَا الْحَدِيثِ، قَالَ: قَالَ الْوَلِيدُ: سَمِعْتُ أَبَا عَمْرٍو يَعْنِي الْأَوْزَاعِيَّ، يَقُولُ: سِرُّهُ أَوَّلُهُ.
The word sirrahu means beginning of the month.
