I think it's good to be argumentative when it comes to defending your religion. But surely we cannot be argumentative with the Lord. Shaykh Abdul Qadir al-Jilani said: "You must not argue with the Lord about how He works in you." That is tauhidul af'al. It's about believing in the oneness of His actions. It's entirely His prerogative.
"The lover (muhibb) of Allah is a guest in His presence, and the guest does not pick and choose his food, his drink, his clothing and all his circumstances ahead of the people of the household. Instead he is always accommodating, patient and easily pleased."
