How is the reconciliation made between the hadith "There is no 'adwa (contagion), no bad omen, no harm from the hama (bird), and no harm from the month of Safar" and the hadith "Flee from the leper as you would flee from a lion"?

The questioner : Noble Shaykh, how do we reconcile his saying (peace and blessings be upon him): with his saying (peace and blessings be upon him): ?

The Shaykh : Yes, we reconcile them by understanding that the negation in his saying: is a negation of what the people of the pre-Islamic age of ignorance (jahiliyyah) believed, namely that contagion has an effect in itself, independent of the decree of Allah (Mighty and Majestic). As for the command to flee from the lion, it is a command to flee from that whose evil is feared, because leprosy—may Allah grant us safety from it—is among the rapidly contagious diseases. Thus, the command to flee from it is a command to take the protective measures, just as we say, for example, "Beware of fire by staying away from it," even though your nearness to the fire and your distance from it are all by the divine decree and destiny of Allah. So the negation is directed at what was customary or believed among them in the pre-Islamic age of ignorance (jahiliyyah), namely that contagion has an effect in itself. And for this reason.
