Question
What is your ruling on the hadith in Nisai Shareef about Ghazwa tul Hind. Are the hadith authentic & also whether this Ghazwa has already taken place in the past or will take place in the future. It would be appreciated if the answer is descriptive and explanatory.

Answer
…This Hadeeth in which the conquest of India is mentioned was reported by An-Nassaa’i, Ahmad, Al-Bayhaqi and others from Thawbaan may Allaah be pleased with him and Shaykh Al-Albaani may Allaah have mercy upon him classified it as Saheeh in “Saheeh Al-Jaami’”.
Besides, Ibn Katheer may Allaah have mercy upon him said in his book “An-Nihaayah Fil-Fitan Wal Malaahim”: “Indeed, the Muslims conquered India in 44 (A.H) during the reign of Mu’aawiyah Ibn Abi Sufyaan may Allaah be pleased with him and some incidents took place and we mentioned them in detail. Also, the great king As-Sa’eed Al-Mahmoud Ibn Subiktikeen, the ruler of Ghaznah and its surroundings conquered it in about 400 (A.H) and he did there some renowned acts and good matters and he broke the great idol called “Somnath” and took its garlands and swords and returned to his country victorious and safe.”
4. The Hadith of attack on India is Sahih but it has already been fulfilled. Hadith was referring to the attack on India by Muhammad Bin Qasim which has already happened. So no divine planning of forcefully capturing Indian again!
