Assalamalekum, In my family, if any family member is going out for any thing, usually elder member they read some surah and blow on the people who are going out. This is basically for the safe journey. Is it a right practice?
All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
It is more appropriate in this regard to apply the Sunnah in bidding farewell to a traveler as this is a means of protecting him/her from evil. Ibn ‘Umar, may Allah be pleased with him, narrated that when the Prophet was to bid farewell to a man, he would hold his hand and he would not leave it until the man himself dropped the Prophet’s hand, and he would say to him: “Astawdi’u Allaha deenaka, wa amaanatika, wa khawaateema A’malika.” ‘I place your religion, your faithfulness and the ends of your deeds in the trust of Allah.’ [Ahmad, At-Tirmithi, An-Nasaa’ee and Ibn Maajah]
Also, in another Hadeeth narrated by Ibn ‘Umar, may Allah be pleased with him, as well, the Prophet said: “When Allah is entrusted with something, He would preserve it.” [Ahmad]
As regards what is mentioned in the question, it appears - Allah Knows best – that it is permissible to do it without believing that it is a Sunnah to do it.
Allah Knows best.
