Sikh empire turned Badshahi masjid into a stable for horses and pigs, and desecrated Islamic shrines.
.
Transforming of Mughal Masjids into stables by Sikhs was a deplorable act, no doubt.
But have you forgotten what Mughal Kings did to Sikh Gurus and their children? or what Ahmad Shah Abdali had done to Sikh Gurdawaras, esp. the holiest of them for Sikhs, the Golden Temple; blew up the building and filled the pond with ****.
Ranjit Singh, later on, handed Muslims most of their mosques back. He even gifted all
Nowadrat (Islamic Relics) to the respectable Fakir Family (of Lahore) instead of destroying or desecrating them. Today, Fakir Khana is the largest privately owned museum in South Asia.
The man in charge of the treasury as well as the arsenal of the Sikh empire during Ranjit Singh's era was a Muslim. Ranjit Singh's Foreign Minister was also a Muslim. Many of his emissaries were Punjabi Muslims too.
Many Punjabi Muslims held high posts in Ranjit Singh's Punjab. He was a secular ruler. One of his Muslim generals, Elaahi Bukhsh of Lahore, the in-charge of Khalsa Artillery, was the man behind the defeat of Sayyad Ahmad Shaheed's Yousafzai Army in the famous battle of Balakot. It was not about Muslim Vs Non-muslim as many people try to make it look like. With a few exceptions, those wars were fought just for power, territory and wealth.
What did the Afghans do in Punjab, other than indiscriminate loot and plunder?
And here we have people issuing Fatwas of
kufr against those who opposed Afghani dacoits!!
