When I was so small viz 13 or may be 14 year old, I lied to all my family about a dream which I haven't seen ever. That dream was a religious dream I told my whole family that I saw this and that which was totally wrong and a lie. This was the biggest lie of my life bt I remembered it today. Please tell me if Allah and RasullAllah have forgiven me or not because I was so small at that time and know I do astaghfar also. Please kindly tell me that if there is any kaffara for that dream which I can give?

Allah is all mercy and every mercy and once aperson repents with the depth of heart, the sins are excused
