Assalamalekum, In my family, if any family member is going out for anything, usually elder member they read some verses of Holy Qur'an and blow on the him/her who is going out. This is basically for the safe journey. Also some people are throwing water after a family member he/she is going out in a journey.... Is it a right practice?
All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad sallallaahu `alayhi wa sallam (may Allaah exalt his mention) 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 Allaah be pleased with him narrated that when the Prophet sallallaahu `alayhi wa sallam (may Allaah exalt his mention) 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:
" أَسْتَوْدِعُ اللَّهَ دِينَكَ ، وَأَمَانَتَكَ وَخَوَاتِيمَ عَمَلِكَ "
“Astawdi’u Allaaha deenaka, wa amaanatika, wa khawaateema A’malika.”
‘I place your religion, your faithfulness and the ends of your deeds in the trust of Allaah.’ [Ahmad, At-Tirmithi, An-Nasaa’ee and Ibn Maajah]
Also, in another Hadeeth narrated by Ibn ‘Umar may Allaah be pleased with him as well, the Prophet sallallaahu `alayhi wa sallam ( may Allaah exalt his mention ) said: “When Allaah is entrusted with something, He would preserve it.” [Ahmad]
As regards what is mentioned in the question, it appears - Allaah Knows best – that it is permissible to do it without believing that it is a Sunnah to do it.
Allah Knows best.
