Sameer Sahib said he had not seen his daughter since November, but on Wednesday last week Nikat called him to come and visit.
He said when he saw them the next day, the pair looked "bubbly", Sanaya seemed "all right" and he had no concerns.
Mr Sahib described the toddler as a "beautiful, cute girl".
"She was just such a bubbly girl. I didn't have much time to play with her, just a life cut so short," he said.
"She always used to wait for me to come back from work. I can't explain it [the heartbreak].
"We will miss out on all the fun things in life, taking her down to the park. Buying her a car, getting her married."
"I couldn't believe it, I just froze."
He said he found it "really tough" to identify her body.
"I never thought I'd do that in my whole life, not to my own daughter," he said.
Mr Sahib said he had recently bought gifts for his daughter after travelling overseas, including a pink children's couch, but never got the chance to give them to her.
