then he should have mentioned it along with his answer to the matter, so that the reader might have a clear understanding of the issue.
One of his strange assertions is that, in support of his view, he cited what he transmitted from Abd al-Razzaq in his Musannaf (2/519), through the route of Dawud ibn Abi Asim, who said: “I asked Ibn Umar about prayer while travelling, and he replied: ‘Two rak'ahs.’ I said, ‘What do you say when we are here in Mina?’ He said, ‘Woe to you! Have you heard the Messenger of Allah, may Allah bless him and grant him peace, and believed in him?’ I said, ‘Yes.’ He said, ‘Then he used to pray two rak'ahs. So pray two rak'ahs if you wish, or leave it.’”
I say: Its chain is authentic. Ibn Hazm then stated: “This is a clear indication that Ibn Umar instructed the traveller to pray only two rak'ahs behind a resident imam.”
I say: This is an astonishing interpretation, and a remarkable lapse in understanding from such an astute imam. As you can see, this report makes no mention whatsoever of an imam, whether he is travelling or resident. At most, it indicates that, after Ibn Abi Asim heard from Ibn Umar that the prayer while travelling consists of two rak'ahs, he wished to seek clarification concerning prayer while they—that is, the pilgrims—were at Mina: would they shorten it there as well? Ibn Umar answered in the affirmative, explaining that the Prophet, may Allah bless him and grant him peace, used to pray two rak'ahs there. This is all that can be understood from the report, and it is how those who recorded it understood it. Thus, Abd al-Razzaq included it under the chapter “Prayer While Travelling,” among hadiths and reports concerning the shortening of prayer. Likewise, Ibn Abi Shaybah included it in the chapter “Those Who Would Shorten the Prayer” in his Musannaf (2/451).
This Dawud ibn Abi Asim was a Meccan from Taif. It is therefore possible that, because he was Meccan, he had some doubt, since the distance between Mecca and Mina is short. Ibn Umar answered him as stated above, apparently meaning that the Prophet, may Allah bless him and grant him peace, shortened the prayer at Mina, as did the Meccan pilgrims who were with him. And Allah knows best.
