The Heat played without forward P.J. Brown, who sat out his one-game suspension for leaving the bench during a scuffle in Miami's 89-83 loss to the Knicks on Sunday.
It was Mourning's hard foul on New York's Larry Johnson that touched off that incident. On Monday night, Voshon Lenard knocked Atlanta center Dikembe Mutombo out of the game with a flagrant foul late in the fourth.
With 3:59 left and Miami up 85-77, Lenard fouled Mutombo as he was attempting a dunk. Mutombo, who landed hard on his back, walked off on his own but did not return.
Isaac Austin had 11 points starting in place of Brown, who also was fined $2,500. Tim Hardaway had 11 points and 13 assists as the Heat beat Atlanta for the third straight time.
Mookie Blaylock led the Hawks with 20 points, while Steve Smith had 17 -- 12 in the first quarter. Mutombo had 14 points and 15 rebounds.
Mutombo and Blaylock ignited a 13-2 run to cut a 15-point Miami lead to 64-60. Mourning dunked emphatically on Mutombo to spark a 9-1 run as Miami took a 78-69 lead after three quarters.
Lenard scored 13 points during Miami's 23-7 run spanning the second and third quarters as the Heat led 62-47.
