ڈاکٹر محمد ضیاء الدین انصاری
ڈاکٹر محمد ضیاء الدین انصاری میرے مخلص اور عزیز دوست تھے، مجھے ان کے انتقال کی خبر بہت دیر سے ملی، وہ علی گڑھ مولانا آزاد لائبریری میں ڈپٹی لائبریرین تھے، وہاں جاتا تو مطلوبہ کتابیں فوراً حاضر کرتے اور چائے سے خاطر تواضع کرتے، اصرار کرکے گھر بلاتے اور پرتکلف دعوت کرتے، خدابخش لائبریری کے ڈائریکٹر ہوکر وہ پٹنہ گئے تو اسے ترقی دینے کے لئے متعدد کام کئے اور کئی سمینار کرائے جن میں مجھے مدعو کرتے، وہاں سے ریٹائر ہوکر علی گڑھ آئے تو مولانا حسین احمد مدنیؒ پر ایک سمینار کا پروگرام بنایا مگر وہ نہ ہوسکا، ضیاء الدین صاحب کو علم و ادب سے بڑا شغف تھا اور وہ اچھے منتظم بھی تھے، کئی کتابیں لکھیں لیکن اشاریہ نگار کی حیثیت سے انہوں نے اپنا خاص سکہ جمایا، وہ بڑے شریف، نیک طینت، خوش خلق اور مرنجان مرنج شخص تھے، اﷲ تعالیٰ انہیں جنت نعیم عطا کرے اور پس ماندگان کو صبر جمیل عطا فرمائے، آمین۔

The aim of Hijrah is philosophically viewed as a way to spread Islam wisely. This was by Allah’s guidance and directive amidst the very bitter atmosphere in Makkah at that time against the early followers of the Islamic religion brought by the Rasulullah (pbuh). The prophetic Hijrah observed from the way it impacted Makkah and Madinah’s societies can be construed as a very important event that provided us with a variety of messages. It also acts as a reflection of our contributions to da’wah and the roles we can assume as good Muslims, by looking at what the Rasulullah (pbuh) and his companions had themselves sacrificed in the Hijrah. In short, Al-Hijra is the time when the Prophet Muhammad (pbuh) and his followers moved from Makkah to Madinah, where they set up the first Islamic state. Islam needed to expand and spread in the world, so the migration resulted in the expansion and preservation of Islam and Muslims. The Rasulullah (pbuh) migrated to Madinah when his enemies in Makkah mistreated him and his followers. It is a fact that the early Muslims in Makkah were greatly troubled by the unbelievers of Quraisy, the tribe of the Prophet (pbuh). The Rasulullah’s (pbuh) popularity in his da'wah efforts to invite his people to Islam was seen as threatening by the people in power in Makkah. The context of Hijrah was seen as urgent and timely as the unbelievers in Makkah had escalated the persecution against Muhammad (pbuh) and his followers. This persecution and a directive from Allah were the main reasons for the migration.
Human body is very delicate towards harsh environmental variations. High energy UV radiations intentionally or unintentionally interact with our skin and eyes, causing some acute effect such as, photokeratitis, skin aging and also some chronic effects like melanoma skin cancer and DNA damage. Clothing is an important precautionary measure to combat with these damages, but low weight and high porosity of cotton fabric make it unfit for protection against UV rays. Hence, to improve the protection factor of white cotton fabric, computational approach was utilized to search the effective UV absorbers for cotton fabric. The Density Functional Theory (DFT) theory with three functionals was utilized to study the design molecules and results indicated that all the five design molecules (1-5) absorbed inthe UV region of the solar spectrum. These deigned molecules were synthesized via a condensation reaction and their structure confirmation attained through UV/Vis., FTIR and ESI-MS analysis. The theoretically calculated λmax and experimental λmax of all the five UV absorbers were in close agreement. The cottonfabric was treated with designed and synthesized UV absorbers via the exhaust method of dying and its processing conditions optimized by adapting a statistical design “central composite rotatable design” of response surface methodology. The outcomes directed that all the synthesized molecules showed 65-78 % exhaustion and 62-80 % fixation at the acquired optimized conditions. Maximum exhaustion with cotton fabric was presented by 1 and minimum shown by 5. The protection factor of the treated cotton fabric was assessed and results directed that the treated fabric with 1-4 fells in the very good Ultraviolet Protection Factor (UPF) range at 3 % concentration while fabric treated with 5 fells in good range. The UPF increased as follows: 5 <4 < 2<3<1. Whiteness index test results revealed that all the synthesized molecules did not decrease the whiteness of the fabric as much at 3 % concentration, but after exposition to light fastness testing decreased its whiteness little bit as compared to standard. Washing test results indicated that UPF of treated fabric decreased after washing process, with UV absorbers (1-4), it remained in the very good range of UPF after ten washings. While the 5 showed more reduction in UPF value after washing. Degradation studies revealed that synthesized molecules were degradable by safer advance oxidation process technology. Current study opened a new prospect for search of such molecules having more persistent nature after laundry action.
