Bismillah wa salatu wa salamu ala rasulullah.
Salam alaikum wa Rahmatullah.
Shaykh and muhadith of Rawafid – al-Kulayni narrated in his al-Kafi 1/279:
From Muhammad ibn Sinan who has said the following: “Once I was in the presence of abu Ja‘far the 2nd (alaihi salam), and I mentioned the differences among the Shi‘a. “The Imam said, ‘O Muhammad, Allah, the Most Holy, the Most High, is One and eternal. He created Muhammad, Ali and Fatimah, recipients of divine supreme covenant. They were there for a thousand Dahr . Then He created all other things. He made them witness the creation of all other things. He made obedience to them obligatory and gave them control of the affairs of the creation. They can, thus, make lawful whatever they wish and unlawful whatever they wish and they never wish anything unless Allah, the Most Holy, the Most High, wishes.’ He then said, ‘O Muhammad, this is a religion that, if exaggerated, will lead to disproportionate belief and ignoring it will cause degradation. Those holding to it properly will have proper contact. Keep it with you, O Muhammad.’”
So basically this is a fundamental for shias, which do believe in the Wilayah at-Takwiniyah. This reports clearly states that Imams are in the control of the universe. I am asking shias, if rain is a matter from the matters of the universe? Yes, will be an answer. So, you have to ask for the rain, the one who controls it?
Also this narration clearly says that Imams are permitted to play with shariah as they wish. They can make things lawful and unlawful. Reservation that they don’t wish until Allah doesn’t wish play no role. Because nothing in world can’t happen, unless Allah wish it. I am not going to get deeper in the matter of qadar.
Tayib, ya ayuha shia! You say Imams can make things lawful and unlawful. I say, is shariah – religion, perfected in the times of prophet (sallalahu alaihi wa ala alihi wa sallam)?! If answer is no, then you are disbelievers which rejecting Quran. Because in Quran surah al-Maida, Allah clearly said that religion was perfected – completed. Khalas! No one on earth can change lawful or unlawful if religion is perfected and complete!
