Hazrat Jaabir R.A. says I heard the Messenger of Allah say: ‘zamzam is a cure for any purpose for which it is being drunk’.
Another Hadith states: ‘If you drink it to quench a thirst, it will do so, and if you drink it to fill stomach in place of food, it will do so, and if you drink it for a cure from some illness, it will do so. This is the service of Hazrat Jibraeel A.S. and it is the way of Hazrat Ismail A.S. (Ithaaf)
The meaning of ‘service of Hazrat Jibraeel A.S’ is that it was through the striving of Hazrat Jibraeel A.S. that this well was opened up. The story is well known. Hazrat Sufyaan bin Uyayna R.A. was a famous muhaddith; once a man visited him saying; ‘do you believe that the following saying of Rasulullah Sal’am is a correctly reported hadith: “Zamzam is a cure for anything for which it is being drunk’. Hazrat Sufyaan R.A. replied: ‘yes it is correct’. The man said:’Well I have drunk Zamzam for this purpose that you shall dictate to me two hundred hadith’. Hazrat Sufyaan R.A. told the man to sit down and recited two hundred Hadith, and also said: ‘Hazrat Umar R.A. used to say while drinking Zamzam: ‘O Allah I drink this now with the intention of quenching the thirst of the day of Qiyamat’ (Ithaaf, Kanz)
At the time of the farewell Haj Rasulullah Sal’am drank a lot of Zamzam and said: ‘My hearts’ desire is that I fill the bucket myself and drink, but I fear that all the people will want to do the same, therefore I am not filling the bucket myself. According to some reports Rasulullah Sal’am did fill the bucket. Perhaps he did that at one time, and when there were many people, he said as reported above. Once Rasulullah Sal’am asked Hazrat Ibn Abbaas R.A. to bring some Zamzam. Hazrat Ibn Abbaas R.A. replied that there was some clean water in the house, which he felt would be better to give since so many people hands touched this water. Rasulullah Sal’am said: ‘No give me of that which all drink’. Hazrat Ibn Abbaas R.A. brought from that water, and Rasulullah Sal’am drank, and threw it over his eyes, he then took and drank a second time and again threw some over himself’. (Kanz)
Rasulullah Sal’am also said: ‘between us believers and the hypocrites there is this difference that while we can fill ourselves with Zamzam they can only drink a little. Another Hadith says: ‘Once Rasulullah Sal’am commanded that a pail be filled with Zamzam. The pail was placed on the edge of the wall. Rasulullah Sal’am took the pail and said: ‘Bismillah’, and drank for a long time; then he took the pail away from his mouth and said: ‘Alhamdulillah’. Thereafter, he again said: ‘Alhamdulillah’. Then he said: ‘The difference between the hypocrites and ourselves is that they cannot drink a lot of Zamzam’.
Rasulullah Sal’am said: ‘Perform salaat on the salaat places of the righteous and saintly ones and drink of their water’. The companions inquired: ‘O Messenger of Allah, what are the salaat places of the saintly ones?’ Rasulullah Sal’am replied: ‘Beneath the Meezabur Rahmah’. Then the companions inquired: ‘And what O Messenger of Allah is the water of the saintly ones?’ Rasulullah Sal’am replied: ‘Zamzam’. (Ithaaf)
Hazrat Um Maa’bad R.A. relates: ‘A young man once passed her tent carrying two waterbags. I asked him: “What are these two bags?’ he replied: ‘A letter from Rasulullah Sal’am came to the chief of our tribe wherein was requested that Zamzam should be sent to him in Madina. I now intend delivering these two bags filled with Zamzam to him with the greatest possible speed so that the water does not dry up.’ (Ithaaf)
Hazrat Aa’isha R.A. used to carry Zamzam with her from Makkah and related that Rasulullah Sal’am himself used to carry Zamzam with him. According to the Hadith Rasulullah Sal’am used to carry Zamzam with him, and he used to sprinkle it on the sic k ones, and at he time of tahneek of Hazrat Hasan R.A. and Hazrat Hussain R.A. he gave them to drink. (Sharh Lubaab)
(Tahneek means to place something in the child’s mouth for the first time after birth)
With regard to the virtue of Zamzam, I could do better than to mention that at the time of Mi’raaj, Hazrat Jibraeel A.S brought from paradise a golden plate and came with the Buraaq from Jannat. But for washing out the Holy Prophet’s heart, he used Zamzam from Makkah. Whereas he brought so many things from heaven, he could also have brought water from paradise.
Hazrat Ibn Abbaas R.A. reports that when Rasulullah Sal’am drank Zamzam he said the following prayer:
‘O Allah, grant me beneficial knowledge, abundant sustenance and a cure from all diseases.’
