Azmi, 66, and Kapur, 70, took to Twitter to show their concern for the minister's health.
"Our best wishes for an early recovery Sushma Swaraj. It's so rare for a leader to announce factual health status. Respect for your courage," Azmi wrote.
While, Kapur tweeted, "@SushmaSwaraj praying for your speedy recovery..."
Swaraj on Wednesday underwent tests for a transplant, and gave information about her health condition on the micro-blogging site.
"Friends: This is to update you on my health. I am in AIIMS because of kidney failure. Presently, I am on dialysis. I am undergoing tests for a kidney transplant. Lord Krishna will bless," she wrote.
