Some ulama say that the tie is not the symbol of the cross, hence it is permissible to wear it.

Answer

They are juhala. Ulama do not talk such drivel. Ulama do not lead Muslims into the "lizard's hole" in a mad stupor of emulating the stupidities of the kuffaar. The tie is the symbol of christian cross. Furthermore, it is not permissible to emulate a specific kuffaar dress style even if we assume that it is not a symbol of the Christian cross. To imitate such a futile, stupid dress style of the kuffaar is most unbefitting the dignity of Imaan. Only corrupted brains discern respect and honour in such stupid dress styles of the kuffaar. Due to mental slavery and western indoctrination, Muslims of this era consider it honourable to stand and urinate in the public like donkeys. Thus, the brainwashed – brainwashed by the Americans – rulers of Saudi Arabia have fitted standing urinals in Mina for the Hujjaaj to lift their Ihraam garb, and stand to urinate in full view of the public. Even women pass by and observe these jaahil hujjaaj with their satr exposed urinating like donkeys and cattle.

The lamentable disease is gross inferiority of the brains which strive to achieve honour and respect by baboonically imitating the western kuffaar in almost every stupid, lewd and filthy practice they innovate. For such people dwelling in bewilderment in the baboonic cult, the Qur'aan Majeed says: "What! Do you search for honour from them? Verily all Izzat is for Allah."
