Obey a person as he is infallible,"According to the Quran and Hadith, no human being is infallible, and Muslims are not allowed to obey or follow anyone who claims to be infallible. 
    Here's a brief analysis: Quranic Verses: Ayah 31 of Surah At-Taubah (9:31) states: ""They have taken their scholars and monks as lords besides Allāh, and [also] the Messiah, the son of Mary. And they were not commanded except to worship one God; there is no deity except Him. Exalted is He above whatever they associate with Him. 
    In the first verse (31), it has been said that these people have taken their rabbis and monks as gods beside Allah and they have done the same with Sayyidna ` Isa ibn Maryam (علیہما السلام) whom they have given the status of their Lord. This is, of course, obvious in the case of Sayyidna ` Isa (علیہ السلام) whom they took to be the son of God and did not demur from saying so. As for the charge against them that they had taken their rabbis and monks as gods, it has its reason. They used to call them as their Lord in clear terms, but even if it is presumed that they did not believe their religious leaders to be their gods, they had virtually transferred to them the right to be obeyed which is the right of Allah Jalla Thana'uh, absolutely and exclusively. They would, so to say, follow the dictates of these leaders under all circumstance - even if their dictates happen to be against Allah and His Messenger. With that attitude, one is bound to land in a valley of no return. How can one go about obeying someone even if that person says things contrary to the dictates of Allah and His Messenger? And how can one who has reached this ultimate limit still not refuse to obey that person? This is like taking someone as god - an act of flagrant blasphemy, an open kufr."
Charging interest for loans,"According to the Quran and Hadith, charging interest for loans to anyone (muslims or non-muslims) is considered prohibited and unjust. Here's a brief analysis:
    Quranic Verses:
    Ayah 275 of Surah Al-Baqarah (2:275) states: ""Those who consume interest will stand ˹on Judgment Day˺ like those driven to madness by Satan’s touch. That is because they say, “Trade is no different than interest.” But Allah has permitted trading and forbidden interest. Whoever refrains—after having received warning from their Lord—may keep their previous gains, and their case is left to Allah. As for those who persist, it is they who will be the residents of the Fire. They will be there forever."
Cut a man beard,"the commandment to maintain beards for Muslim men is to distinguish between Muslims and polytheists. Here's a brief analysis:
    Hadith:
    Ibn ‘Umar reported God’s messenger as saying, ""Do the opposite of what the polytheists do ; let the beard grow long and clip the moustache.” A version has, “Cut the moustache down and leave the beard.”."
Playing & listening to music,"It has been decisively prohibited in Shariah, as the evidences mentioned further along will show. Yet there are individuals that are not ready to believe that it is Haram.
    Allah Most High says:
    “And there are among men, those that purchase idle tales, to mislead (men) from the path of Allah and throw ridicule. For such there will be a humiliating punishment” (Surah Luqman, V. 6).
    The great Companion Abd Allah ibn Mas’ud (Allah be pleased with him) states in the explanation of the word “idle tales”:
    “By Allah its meaning is music” (Sunan al-Bayhaqi, 1/223 & authenticated by al-Hakim in his Mustadrak, 2/411)."
Garment below the Ankles (Isbal),"Imam An-Nawawi (Rahmatullah ‘alayh) comments on the following hadith in his Sharh of Sahih Muslim: “Verily Rasulullah (sallallahu ‘alayhi wa sallam) said, ‘Allah will not look to whomever drags his garment out of khuyala‘ (pride, boast, arrogance).”
    “And it is not permissible to lower [the garment and the turban] below the ankles if done out of arrogance. And if it is done out of other than arrogance, than it is makruh (disliked), and the apparent meanings of the  narrations that discuss letting the garments down below the ankles are in reference to it being done out of arrogance. And there is a nass (legal proof) from Imam Ash-Shafi’i that states he made a distinction between the two cases. And there is consensus (ijma‘) of the ‘Ulama’ that it is permissible for women to let their garments down (Isbal). And it is authentic from the Prophet (sallallahu ‘alayhi wa sallam) that he gave permission to the women in lowering their garments and arms length. And Allah Knows Best!”"
