Why did Allah Almighty say: " إلا بحبل من الله وحبل من الناس" (except through a rope from Allah and a rope from people), and not: "ثم حبل من الناس" (then a rope from people)?

The conjunction using "wa" (and) in His (Allah's) saying, "إلا بحبل من الله وحبل من الناس" (except by a rope from Allah and a rope from the people), does not resemble the blameworthy conjunction in "ما شاء الله وشئت" (what Allah wills and you will). This is because willing belongs to Allah alone, whereas "wa" is permissible in other actions, such as opposing, obeying, and enriching, as in His (Allah's) saying, "أَطِيعُواْ اللّهَ وَرَسُولَهُ" (Obey Allah and His Messenger), and "إِنَّ الَّذِينَ يُحَادُّونَ اللَّهَ وَرَسُولَهُ" (Indeed, those who oppose Allah and His Messenger), and "وَمَا نَقَمُواْ إِلاَّ أَنْ أَغْنَاهُمُ اللّهُ وَرَسُولُهُ" (And they resented not except that Allah and His Messenger enriched them). This is because obedience to the Messenger and disobedience to him are subordinate to obedience to Allah and disobedience to Him. As for willing, it belongs to Allah alone, not His creation.
