SB 7.5.36
visnor va sadhv asau kim nu
karisyaty asamañjasah
sauhrdam dustyajam pitror
ahad yah pañca-hayanah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Although Prahlada is only five years old, even at this young age he has given up his affectionate relationship with his father and mother. Therefore, he is certainly untrustworthy. Indeed, it is not at all believable that he will behave well toward Visnu.
