What is the evidence for the opinion on combining the two prayers?

The questioner : What is the evidence for this?

The Shaykh : If there is evidence in it. Ali. This is a comment. Yes, Ibrahim. Correct, this is evidence, a reasoning, because the time of the first prayer has ended before his conscience became occupied with this obligatory duty, is that so? A third piece of evidence is the analogy to the first issue: if the obligation were lifted after the time of the prayer that is combined with the one following it had entered, he would only be required to perform the prayer whose time he caught, only the prayer whose time he caught. So these two are the same; this and that, both are the same. As for the report (athar) narrated from 'Abd al-Rahman ibn 'Awf and Ibn 'Abbas (may Allah be pleased with them), that is their opinion, their opinion, and it is not a matter of scholarly consensus. Yes, how? If they are weak, then praise be to Allah. Well done, may Allah bless you. In any case, this strengthens our position in adopting the correct opinion, even though Imam Ahmad used them as evidence, and his use of them as evidence indicates that he considered them authentic. But praise be to Allah, after their being graded weak, it misleads us regarding adopting them.
