The Sultan was accompanied by Selangor Menteri Besar Datuk Seri Mohamed Azmin Ali and was welcomed by Deputy Menteri Besar Datuk Mohd Amar Nik Abdullah.
The Ruler arrived at 2.30pm and spent more than 30 minutes before leaving Ahmad's residence.
In April, Ahmad was admitted to Hospital Universiti Sains Malaysia (HUSM) Kubang Kerian after complaining of fatigue after chairing the state exco meeting.
Ahmad then underwent operation on April 14 after doctors found blood clot in his head.
Following the surgery, the MB was ordered to rest until his next doctor's appointment.
Mohd Amar is discharging the duties of Ahmad in the absence of the MB.
